I am talking about future titles. Not released titles, 2K is not using GFWL anymore, THQ is using Steamworks now. GTA and Dawn of War expansions are using GFWL because the base game is using GFWL so they can't change it. For me GFWL is crap, I hope it can't see the future and Microsoft will stop killing the PC gaming.

Oh, sorry, I was just thinking in terms of how many titles there are, not actual publisher support. :o You're quite right.
Many games on Games on Demand have GFWL only on that release and not on any other, similar to non-Steamworks Steam enhancements, but the crucial difference is that this is required in order to sell a game through GoD. Since Steam is so much more popular I can't see publishers integrating both this and Steam integration, especially since more and more are going with full-on Steamworks (which is applied to all releases of a game). So far there has been no game using both Steamworks and GFWL (fortunately) and I doubt there will ever be one.
Fable III alone can't save Games on Demand unless Microsoft is going to start bringing all their big exclusives to the PC (as has been rumoured for Alan Wake and Halo: Reach). In the short term they will definitely lose money either way, however, as many gamers refuse to buy from anywhere but Steam (or Direct2Drive, or whatever their chosen service is).

It really baffles me we are getting this and not Fable 2. I mean, I played some of Fable 2 and it was not that great, but still, WTF?
I am happy to see MS releasing a PC game again, and at the same time it seems too, but Fable 3 is an odd jump-to choice, and pretty much rules out ever getting Fable 2 on PC.
Watch Halo Reach get a PC version without Halo 3 ever being ported.

Dawn of War II?

This is not at all unusual; for instance Dead Rising 2 and Saints Row 2 are for PS3 and PC as well despite the previous entries being 360 only. This makes it really difficult to follow the story in order, although with modern games they often include flashbacks and whatnot so players new to the series don't feel left out.
The most you can hope for for a real catch-up is for the missing game to be enhanced and re-released on the new platform, but this won't happen until the game in question is a few years old.
Sorry, I was specifically meaning for providing added functionality (multiplayer, achievements, etc.) not DRM. One of the advantages of Steamworks is that it can provide various levels of functionality, whereas GFWL is all-or-nothing (you can't just use the inherent DRM component).

I meant baffles more as in "why is Microsoft suddenly supporting the PC again? Why are they releasing this day and date when all their previous ports have been a year or more later? Why not port Fable 2 to coincide with Fable 3 on Xbox?"

wat? 55 Euros?
BWAHAHAHAHAHA, this joke made my day. Oh wait, that is not a joke.....

Are you planning on paying the full price? Wait a year or so and you'll get it for 30e, another year and it's 15 or 10e. That's what I'm gonna do anyway, so many good games to play that the new ones can wait till they become affordable.

Well, part of the reason may be that Fable III's multiplayer is seemingly cross-platform (a Lionhead job posting for the PC version had tasks including "ensure the PC and the Xbox 360 builds can interoperate”). MMOs have always been strongest on the PC, and they may be betting that Fable III's pseudo-MMO features and accessible gameplay will appeal to this audience. If they plan to launch a full-on Fable MMO later on that would certainly be on the PC, so giving PC players some Fable games early is a great way of getting them familiar with a series they might not otherwise have access to.
As for skipping Fable II, if the PC version of Fable III is going to launch simultaneously with the 360--which seems to be the case judging by the badge on the cover (IIRC all previous games with this had both versions out at the same time)--there isn't enough time between now and then to get a PC version on the market without it detracting from the sequel's sales (especially with a Dragon Age sequel arriving around February 2011).
It also seems like Microsoft is going to move back to making PC releases in general. This has been rumoured for Alan Wake and Halo: Reach, two other big exclusives which, like Fable, had their previous instalments only on the 360. While those two are just rumours, they have also recently released the Game Room and Games on Demand features for the PC--previously all new Live features were only on the 360.
If so this is a curious change of pace, because a Microsoft executive once stated that "If we launch a game that is on 360 and PC simultaneously, we basically shoot ourselves in the foot by allowing the German market to choose to play the PC version ... If we launched a Halo game on PC and 360 in Germany simultaneously, 80 per cent of sales would be on the PC". It's possible that they now are content enough with the 360's market position to release PC games again.
EDIT: another possibility is that they are wagering that doing this will hurt the PS3 more than it does the 360; while having Fable and the like on the PC gives PC gamers one less reason to get a 360 it also gives them one less reason to get a PS3--especially if playing these gets them interested in the 360 library in general and the games that haven't made the jump to the PC yet. It also opens up the possibility of bringing older first-party 360 games to the PC (like how we got Halo 2 several years late).
Regardless of their motives--which we may never know for sure--I'm very happy with the direction Microsoft seems to be taking.
Look on the bright side: at least they aren't charging console-level prices for the PC version like Activision and Ubisoft have doing been of late--better yet, buy those games via Steam or Direct2Drive.eu and pay even more!

Nope, 55€ it's a no go.

Same here, it's just that as a PC-only gamer, it would suck to forever miss out on Fable 2, Halo 3 and Gears of War 2 and then get Fable 3, Halo Reach and Gears of War 4. We started all those stories, will miss the middle, then see the end? That's frustrating.

Since I only game on PC any release is better than none. If I have to play Fable 3 before Fable 2 I would still buy both, assuming I enjoy 3 anyway. Same with Halo and Gears.
I just have a feeling we won't see those middle installments... they will be considered old news and not worth porting, similar to Call of Duty 3 (which didn't really bother me as that series has self-contained installments).
We might be getting ahead of ourselves too, Fable might be the only series they start porting again. The original sold well, and as someone else said they are heading in a casual/MMO direction with the series, which makes it more PC friendly.

I'm hoping there'll still be enough RPG to satisfy me...I can't get enough. :)
Also hope it won't be too easy like the last two games, but it probably will...
