Revenue's a given
Well, in 2006 (I played WoW) I remember that Blizzard said that they had more than 9/10 of their people working on WoW. That's 90%, or about 2300 people working full-time on it. That's a pretty big payment roll, and they should have had it close to that for a few years.
Wii Fit had what? 100 people? And they can't have been working on it for ages neither, as it isn't exactly a hard to make game (but that doesn't mean it isn't awesome)
WoW doesn't have 10M paying each month, I think it has had 12M players in total, are you telling me that 85% of the players still play?
Of course, WoW is more profitable, but I don't think as much as people seem to think (at least I think they think they think)
