With a look at the schedule of events on day one, we can reasonably expect to see a preview of the Deathwing encounter (well, more of it), and the most common guess that I've seen so far is that the talent system is going to be overhauled in the run-up to the next expansion. Interestingly, that seems to have been a popular guess even before the BlizzCon schedule was released and all but confirmed that something is afoot. Speaking of expansions, there's the specter of that "World of Warcraft preview" panel this afternoon, and I think we all know what that's going to be about. Sort of.
Pandas? Emerald Dream? Xoroth? Tijuana? Ladies and gentlemen, place your bets.
