By the way, you guys know how RE5 is rumored to be coming out exclusively for the PS3?
I heard a different rumor a while back (I can't remember where).
It suggested the Capcom had finally been made to realize that the PS2 can't handle a port of RE4. So someone looked back in time and saw the old "RE4" that Mikami was originally making for the PS2, which evolved into Devil May Cry. So now they're putting together a game using that as their starting point, and they're going to sell-out and slap an "RE5" name on it, sort of like they did with "RE3" on the PSone (Code Veronica was the "real" RE3), and announce that it's exclusive to the PS2.
Supposedly people are just assuming it's for the PS3, because they don't see how Capcom could put together an all-new game this late in the game for the PS2, but if it's just DMC with zombies and the jump button disabled, then it won't take very long to make.
And you probably shouldn't expect to hear any announcements about Capcom "cancelling" RE4 for the PS2, because that would make them look bad in front of their shareholders. They're most likely just going to drop the subject, and wait for it to die along with the sales of the GameCube version.
