I'm interested to see what Nintendo may come up with in regards to the Wii and DS. But I'm more interested in Square-Enix and (if they are attending) Mistwalker.

As for games, I am very interested in seeing Heavenly Sword, The Last Remnant and the new Metroid. I'd also like to see if they do release anything about Kingdom Hearts 3 -- that would be absolutely awesome, but highly unlikely (I bet).
