I understand and sympathize with those who see an exclusive on another console and want to play it so they hope it'll see a port, but honestly, all this petition crap gets on my nerves (no offense Josel).
IF Capcom decides it's worth the time, effort, and money to mess with the engine and graphics to make it Wii capable, they will. However this idea that gamers have gotten into their heads more and more this generation that if an angry mob can form and threaten legal action, or sign a massive petitions and force a company to produce a product they either don't want to, or feel is a good decision for them buisness wise, is stupid (IMO).
I mean, I'm not unsympathetic. The more hands a good game gets in the better. It's more the petition part that gets me. Tho games like SF4 are designed purely with HD gaming consoles in mind, and would probably take a lot of work to make them capable of playing on the Wii. Capcom vs. Tatsunoku was Capcom's way of saying, "We can't bring SF4 over, but we haven't forgotten Wii owners". I think it's the same with MVC3, with what we're told are in game graphics, it looks to be possibly even more graphical than SF4. I can't see it being a simple port to the Wii.
