The demo for the console IL2 is up on the 360 marketplace (possibly psn as well, hard to say without owning a ps3).
Its surprisingly good given the limitations of the controller, its never going to genuinely compete with a PC copy of IL2 complete with a sweet HOTAS setup and TrackIR but knowing what they had to work with, I'm not sure they could have made it any better. I think they did a hell of a lot better job converting this to a controller than most developers have done converting RTS'
To be honest I don't think I'll play it on anything harder than the arcade mode, at least not for a while but arcade seems to have a fairly decent balance of difficulty to fun, I personally never got shot down because I'm awesome but I was just watching a mate of mine playing it and he managed to get damaged and shot down relatively easily.
I've not tried the realistic or simulation difficulty levels yet but I plan to give them a go soon and be amusingly awful

There's a graphics bump, of course? And will it be out on the PSP (sounds like a funny question, but I do like my combat flight sims on the go)?

Oddly enough I think it is coming for PSP (or DS, some handheld), presumably with no real simulation mode

Great game for console gamers, go and grab it.

I'll be waiting for it on the PC... I enjoyed the first IL-2 thoroughly and am excited for this one to come out!

It won't BE on PC as fasr as I know, this is basically a console conversion of IL2 1946. The next PC one will be Battle Of Britain

I bought Il-2 1946 through a retail store, and with it came an extra DVD
I don't think GOG provides it to you, but it has a pretty in depth look into Battle of Britain
It doesn't go too far, but it basically shows you some new features, like dynamic weather
I do have a feelingg that this game is going to be pretty tough on most machines when it comes out
