To be honest, I don't really like the idea of a port from 360/PS3 to Wii. I love RE, but the Wii games that are multiplat haven't been the greatest on Wii (Need for Speed, Fifa etc..). I know most of this is EA and Simpsons supposedly is great on Wii, but it still will be a graphical downgrade with great controls. RE4 Wii was the ultimate edition for that game.
I'd rather have RE 1-3 complete redone for Wii with the same exellent controls as RE4, 16:9, 480p and better graphics.
