Most likely Capcom is going to do the following:
Launch RE5 as PS3/360 exclusive. I HOPE for a day-and-date launch for both platforms (so we can truely judge which one sells better, rather than one getting the jump, invalidating any sort of ability to see if the 360 version can sell well in Japan @ the same time, and vice-versa with the PS3 model in the US).
IMO, Capcom will see how well RE:UC does before considering a Wii version. I think making a Wii version would be too complicated (as it wouldn't be a simple dumbed-down version).
However, if the PS3/360 versions don't do strongly, and RE:UC does incredible, expect a RE5 offshoot at a minimum. More possibly, we could see like a RE5+ for the Wii, adding to the storyline. That way the Wii gets a "real" Resident Evil ala RE0, and the PS3/360 version is still the definitive version.
Back from the dead, I'm afraid.
