Chyba jednak sie myliłem. Na Gamespot piszą:
"From what we saw of the opening levels, the PS3 version of Vegas is pretty much identical to the Xbox 360 version, not just in gameplay but in visuals as well. Then again, Ubisoft wisely has decided not to fix what was clearly not broken. The modified Unreal Engine 3 graphics engine that powers the game looks unchanged, though the frame rate does seem to struggle a bit more during some of the more intensive scenes. On the plus side, the PS3 version seems to have a bit more physics interactions built into it, as we saw more objects react to explosions and gunfire."
W skrócie: Gra na PS3 wyglada praktycznie tak samo jak na 360. Ma troszeczkę więcej spadków frameratu, ale ma lepszą interakcje z otoczeniem (więcej obiektów reaguje na explozje, strzały).
Dodatkowo:
"While the single-player campaign looks as solid as it did in the Xbox 360 version, the PS3 version will have exclusive multiplayer maps and game modes not seen in the 360 or PC versions of the game--but we'll cover those in our upcoming multiplayer preview. Rainbow Six Vegas will ship for the PS3 later this month."
Czyli PS3 otrzyma kilka exclusywnych multiplayerowych map i trybów.

Wersja na PS3 obsługuje tilta:
"Vegas also makes use of the Sixaxis' motion controls when you use the snake camera.
