(1) I'm not going to lie: I'm definitely looking forward to the giveaways this year. In a perfect world, that would be the Chromebook Pixel, Google Glass, Nexus 5, the Nexus tablet, Google Watch, and a Google TV. But, alas, this isn't a perfect world. Still, I'll be happy with whatever I get.
(2) I'm looking forward to the Keynote for some confirmation of all the rumors that have been circulating: Babel, Android 4.3, and whatever crazy stuff they've been keeping under the covers.
(3) I'm hoping for a cool stunt like last year when they announced Glass.
