It would make lots of money. Valve just favors 360. They were negative about the PS3 version as well.
Too bad, I know a lot of Wii owners who would buy this on release day, but if Valve doesn't want our money, I'll give it to those who do. And yes I could play this on something besides the Wii, I just prefer the Wii controllers.
