While Shibusawa could not comment directly on the capabilities of the PS3, he did state that he expected the visuals between the movie and game to be very similar.
Shibusawa jokingly said he's forbidden to say anything about the capabilities of Sony's next-generation console, but he did say he expects to very closely replicate the appearance of the actors from the film in the game.

I highly doubt PS3 games will look anything like a CG motion picture, but I don't doubt PS3 games will be much more 'cinematic' than today's games.
