This has had me really curious. We all know we'll get an expansion announcement. What will separate this Blizzcon from others, though? I'm trying not to raise my expectations too high. Tali can be somewhat biased at times (not that I dislike him or anything).
Also, I for some reason thought WC3 Reforged was coming out this March, but I was clearly wrong because I can't even seem to find a release date for it.
