Blizzard has promised some BIG news (and also promised it wasn't StarCraft 2, thank god) for September 2 at ECTS. They've reserved rooms for 2 two hour press conferences, and that is A LOT of time. The Diablo 2 announcement was one hour long, and the Warcraft 3 announcement consisted of 2 separate one hour conferences.
What do you guys think will be announced at this conference? I'm guessing that one of the 2 hour sections will have something to do with the upcoming Blizzard movies. Besides that...who knows?
