they go over all that they are doing in sc2 and give us a 3 month time table before they release the game :D
map editor will be delayed till the very end of beta :(
and they also go over unit changes and the hidden units that they are keeping in only single player.
I enjoyed listening hope you all do too
Can't wait for the editor :)
