Any chance of a chromebook pixel update at I/O?

What do you guys think the chances are that Google will update the chromebook pixel in a few days at the I/O? I have a early 2011 MacBook Pro. Nothing is wrong with it, but my parents computer is fried and I want to hand my Mac down to them and get a new machine. I deal with windows computers at work all day and for personal use it isn't my cup of tea. I'll either stick with OS X or get a pixel if it gets updated.
