Well, it's definitly been suggested by consumers. However, Capcom usually just says something like "The wii doesn't have enough processing power." or something along those lines. Having RE5 on the wii would definitely sell more copies and imo can be done (after playing operation havier I don't see why not). But Capcom will either move forward with a new game or possibly try to come out with the whole series (0,1,2,3,5) on the wii.
