I'm honestly shocked at all the low scores for this Direct.
I'll admit that Super Mario 3D World was not what I was expecting, but the gameplay looks awesome. And the four-player co-op looks a lot better than the 2D Mario games -- people won't be constantly getting in each other's way. Mario Kart was a show-stopper. The tracks look brilliant, the new anti-grav mechanics look inspired, and it seems to have a robust online component. Plus new footage from Bayonetta, Wind Waker, Wonderful 101, and "X." On top of that, a new Donkey Kong game from Retro (I'm sure it's not Retro's only title in development) and the first ever Smash Bros. trailer for Wii U and 3DS. Oh, and all of these games are exclusive.
These are some of Nintendo's most popular, successful, and best franchises. There can't be a new megaton EVERY conference. And not every high-profile game for a system arrives within 12 months of the console launch.
