Google I/O this week - what to expect

Google I/O is on Wednesday this week, and it will be very exciting to see what Google will present there. The only hardware I think we will see is an updated Nexus 4 with LTE and 32GB storage, and the New Nexus 7.

We will probably see a lot of cool Chrome stuff, like integrated Google Now, notifications and more. And hopefully the new Babel or Google Hangout the rumor says it will be called. We will not see Android Key Lime Pie though, only Android 4.3.

What do you think we will see?
