Google confirmed the dates on their developer's twitter page, the company hasn’t mentioned any other details on what’s to come at the conference, but we’re guessing that Project Glass will make a big appearance on stage. We’ve seen it in action before at Google I/O 2012, but it’s possible that the company may announce public availability for the product, or a release date.
I/O 2012 was huge for Google. They announced Android 4.1 Jelly Bean, Nexus 7, Nexus Q and Project Glass, updates for Google+, Google Maps, and YouTube. Hopefully we’ll see the same kind of action come this May.
Unfortunately, Google doesn't have nothing on their I/O website, we’ll just have to sit and wait for registration to open in next year.
