Videogamer interviewed Ben Judd BC's producer and asked him about a possible Wii version:
VideoGamer.com: Could the game ever come to the Wii? I'm thinking it might be pretty cool to swing Spencer around with the Wii Remote.
BJ: It will largely depend on what the fans want for the future of Bionic Commando. If the interest is there, of course we want as many people as possible to appreciate this great franchise.
So it sounds as if Capcom is at least willing to consider it. Personally, I'm indifferent on this one, but I know a lot of you want more 'core' games on the Wii and this might be an oppurtunity if someone wants to take on starting a petition or such.
