Android 4.3 tomorrow?

Sundar Pichai is scheduled to speak tomorrow at the D11 conference. Could it be that he would finally reveal Android 4.3 and the white Nexus officially coming on June 10th like it's been rumored? It seems to be a perfect opportunity for Google to announce it. It seems like they are trying to take emphasis off of version number so announcing it at a conference might be perfect. Thoughts?
