Still aiming for a first half of 2010 release, Blizzard finished their twitter chat on Friday, march the 12th, promising us a major content patch as well as the Galaxy map editor by the end of April.
Blizzard are planning on making chat rooms in the new Battle.net, they will be organized after the user's interests; this will not, however, be something we'll see in the beta, but something that will most likely be implemented with a patch after the launch of the game.
They are planning on releasing more 2v2 maps, and also a few 3v3 and 4v4 ones soon. Another interesting point is that they are currently looking at the terran's mech, and will give us balance changes for it as soon as they can. Read the full transcript for all the questions and answers.
