F4LL0UT: Seems so, yes. Dark Omen is one of my favourite tactical/strategy games of all time (beat the campaign and played it a lot on LAN) so it would be one of the best things ever for me if it were re-released on GOG.
I presume that the licensing deal expired ages ago and Square Enix probably has no interest in renewing it. But from what I've heard even if they wanted to renew it, licensing stuff with Games Workshop seems to be pretty tough. I guess on top of that there's a chance that the deal that SEGA took over from THQ after THQ went bankrupt grants them exclusive rights for use of the Warhammer license in video games while Dark Omen was originally published by Eidos and is currently probably owned by Square Enix. So yeah, it's probably a perfect example of legal limbo.
Fever_Discordia: Didn't I hear that some of then have serious compatibility issues too?
There are both legal AND technical issues!
In general yes, but fixes are well known and relatively simple. I own both games and after applying those fixes they work flawlessly on my Win 7 (32) (other people claim that they work on 64 too)
It's amusing how this thread proves that those games were very popular in Poland :)
F4LL0UT: I can only imagine how much trouble the game may cause when trying to run it on modern systems.
Not that hard as it may seem ;) I don't have problems playing them. Shadow of the Horned Rat is definitely my favorite :)
But I would buy them here too!
