There are already too many re-releases of previous RE games this gen I think. Resident Evil 4 got ported for the Wii with new widescreen option, and then Resident Evil Archives (with nothing new added... kind of a bad value IMO).
Still, what they could do is re-release the old RE games with updated visuals, but for Xbox Live Arcade and PSN. The remake of Resident Evil and Resident Evil 0 are probably not going to be re-released too soon.
Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...
