Mostly X, Zelda U and Fire Emblem vs. Shin Megami Tensei.
But mostly, I want Nintendo to surprise us. I'm not interested in PS or XB at this point, so whatever Nintendo announces is what I'm going to have to look forward to. I'll be really bummed if there's no footage of a new Metroid, but what I really want is to be pleasantly surprised. Fatal Frame would be a great thing to see and would really shine with the Wii U gamepad. Other things that would be great to see would be a new Starfox, new FZero or most importantly, a new franchise or two. Let's see something new. Nintendo needs their own Infamous, or Uncharted, or God of War. Their core franchises are getting stale -- we want to see something modern and fresh.
My fear is that they are going to come out and show up 90% stuff we already knew about. The new stuff they'll show us will be party games, or wellness games nobody watching E3 cares the least bit about. And don't spend more than 2 minutes on Smash Bros. It's exciting that it's coming, but it's been so thoroughly covered already in that Nintendo Direct there's no need to talk more about it.
