Though Capcom previously confirmed Resident Evil 5 playability on the PS3, the publisher has a way of backing out on exclusivity deals (go ask GameCube). In a very sensationalized report by GamesIndustry.biz today, Japanese Xbox boss Takashi Sensui refused to "deny fresh rumors that Microsoft has snatched exclusivity" of Resident Evil 5. Oh the publicity a sly smile can generate.
1UP countered the "confirmed" rumor calling it debunked for now: "Capcom was financially burned last generation when they promised the series to Nintendo -- why would they tempt a similar fate with a hardware company whose prospects in Japan are dismal, at best?" Money talks. And word has it that if you get Capcom drunk off peach schnapps they'll do anything.
