From an exact perspective, I'd mention some stuff promised....
- Lots of Devil Arms/Guns
- Interactive missions/Lots of Bosses
- An entirely new character to the series, which was not true
Vauxchen, just like you, I don't own a PS3/X360, and I'll wait for the 1st April for the game on PC. From what I've heard, It will be greater than the two console versions put together, but that has to be seen.
The Crysis game graphics level is true. DMC4 on PC will have that level of video output in the game.
