I'm really intrigued by Monolith's new project. Xenoblade is fantastic, and this looks at the very least like a spiritual successor, if not a true sequel. Not sure how I feel about what looks like the online almost MMO-ish component to it though. But the trailer excited me more than probably anything else they showed in the presentation.
There is evidence to suggest that there were going to be dungeons for Fire Mountain and Ice Ring Isle, but I don't think there would have been one for the third pearl. If there was, it would probably be a water temple and that was taken care of by the Tower of the Gods
I'm excited for Wind Waker: HD, and Zelda U sounds interesting (I loved 4 swords) Pikmin I'm semi curious about, the first one was pretty cool. Couldn't care less about another quick rehashed Mario Kart/Smash Bros and I'm less than optimistic about a new Mario main title unless it's something great.
