The Villager looks like a troll character and I like that and MM being in Smash isnt the biggest surprise but its the right fit.
New Pokemon type is cool and its a Dragon killer
After some time to reflect, I think I'm a bit disappointed with Nintendo's showing, but still optimistic about the Wii U. There are definitely some good games coming for the console, but Nintendo's offerings all seem pretty safe. I would have preferred a 'new' console Mario (akin to Sunshine and Galaxy) rather than a sequel to 3D Land. And two Zelda games were shown, but one is a remake is the other is a sorta remake sorta sequel? If they have a Zelda U to show, they really should have shown it. Smash Bros looks great, but again it wasn't really anything new and everyone knew it was coming. They really needed that big showstopper, but they didn't have one.
Zelda U would have been great, but they perhaps wanted to save it since they have 2 Zelda titles in the works to be released this year.
But yeah overall I am disappointed in Nintendo's showing since there really isn't anything to look forward to until the end of the year or 2014. Come on Nintendo, at least release a new 3DS model.
