what was in 2008? nothing? smash and mario kart were already out. wario land? more nothing?
microsoft had, at least, halo 4, new fable, new forza, new gears, and all that stuff. if nintendo announced new games for all their main franchises, people would be pretty satisfied. microsoft just did all that (aside from the announcing thing- we knew about them beforehand but still).
i think a lot of people are upset because microsoft went and did what they always meant to do, which was to make the xbox the THING to have in your living room that did everything (and beat sony to it). they're still making games, but the point of the xbox project was never for it just to be a games machine.
