Wasn't DMC4 moved to only 360?
This true but it will also stay on the PS3. There are more games that are making appearances on both PS3 and X Box 360 like Resident Evil 5, Final Fantasy 13, Metal Gear Solid and much more. Also, I doubt Soul Caliber 4 is coming to the Wii. I heard the graphics are too good for Wii and the makers would have to make huge changes for the Wii, which isn't worth it.
FF 13 is exclusive again.
As Oneray said though, alot of the titles that would legitimize the PS3 are also coming to the 360.
As for the Ps3's "ultimate graphics power", and such, developers really are not utilizing it, obviously, as so many games are being developed for both consoles.
...
Not even Sony themselves, who's online game dept. is making "The Agency", which looks as though it'd be at home on the Wii in terms of graphics.
