Man if this is true it could mean that SCII is coming out this summer!! Hopefully they make it so, because the replays I have seen of the beta so far looks really polished. Yes some balancing has to be done, but they can do that postlaunch as well. Also as someone mentioned below, summer is low on hot titles so more focus for StarCraft II if they release it then instead of the busy holiday season.
SO please Blizzard, save us from the summer boredom with a StarCraft II release!!
