BlizzCon kicked off this morning with a keynote address that brought some major announcements for some of their games. First, World of Warcraft's third expansion, Cataclysm, was officially revealed. It differs from the previous expansions in that they will not be creating an entirely new continent for players to explore. Instead, the two huge continents from the original game will be going through a literal cataclysm, causing some zones to be destroyed, new ones to become available, and existing ones to be entirely revamped. Big news came for Diablo III as well, with the announcement of the Monk class and a trailer showing how it plays. More details for both games as well as StarCraft II will undoubtedly become available over the next few days, but read on for more about what we already know. If you have any questions, don't forget to post them here.
