It is right in line with previous announcements and releases. And that is assuming they stuck to the same release rate as before. One would expect the releases to come more frequently now. I think it would be a pretty big disappointment to their fans if they didn't release something a little more interesting than discussion about 4.3 which most people going to blizzcon are already familiar with anyway.

Diablo 3, Heart of the Swarm, and WoW: Mists of Pandaria or Emerald Dream or whatever.
