People were expecting them to announce new games, like the rumoured new Animal Crossing and Starfox, or at least show something of the games announced last E3 like Metroid and Yoshi. Instead they dedicated nearly the whole thing to Smash Brothers, which is a great game but pretty niche compared to the Zelda and Mario games that were showcased at their last two E3s. They went into ridiculously nerdy detail (Wii Fit Trainer's face is different!!!!) that nobody could possibly care about too. But Nintendo being a bit awkward and weird is what makes them Nintendo!
