Google I/O speculation

I'm surprised that a thread hasn't been introduced on the forums only a couple of weeks away from the conference. So what do you guys think we will see and take away from Google I/O? Google Glass customer edition? Key Lime Pie? Google shoe haha? Nexus 5? X phone?

I think we will see a lot about Key Lime Pie since in coming months we will see the battle of the OS's since we can presumably speculate that apple will release iOS 7 at WWDC. But I can't say I'm excited about either since I have yet to see anything of either one of these.

So what are your thoughts?
