Of course re5 isn't coming to the wii. It simply can't handle that type of grphics and game play engine. So we are stuck with a wii-make of a rather under rated GCN specific RE title instead.
They know we crave RE5 but it just simply isn't happening unless you're willing to invest in a more powerful console.
I hope they overhaul the game play and make at least aiming wii-mote dependent. although the fixed camera angles could prove to me a problem as well. (that was the biggest change Re4 had from the rest, the behind the person camera instead of the fixed angles to simulate a horror movie)
If they do decide to remake RE0 for the wii they should at least copy the formula of Re4 so the wiimote aiming actually works. Also some new content wouldn't be so bad.
This game could prove to be a sleeper hit amongst wii-owning RE fans. Or it could prove to be another gun survivor (shudder). It's all up to Capcom, so hopefully they'll get it right. They've done well with the wii thus far, so I have faith they can turn out a quality product once again.
