Well, they did have the post on HERE a few days ago that this was the case. However, I just don't know. Atomiswave? CPS3? Which is really stronger... honestly? Sure you can do some neat stuff on Atomiswave, but CPS3 has some insane animation. I mean, look at GGX and then look at SF3. It's a joke how bad the animtion is, nevermind comparing it to SF3. Then again, Atomiswave is a Dreamcast, sort of.... and that pulled off the first two SFs really well.
This is all assuming two things: One, that SF4 will have at least the same animation quality/style of SF3. Two, that this is even coming out at all, nevermind on AW. I think Capcom's long lost it to be able to pull of something so incredible to be half the game that SF3 is, nevermind third strike.
