A WoW raiding team moving into competitive Diablo is something we found surprising. Dedicated gaming is in the blood of these players, so maybe it really shouldn't be surprising.
What we're really curious to see is how many hardcore WoW raiding teams will jump on the Blizzard All-Stars bandwagon when that game launches, too. Will Blizzard All-Stars support that sort of competition when it launches? Will we see a real e-sports scene grow from it, like League of Legends currently supports? And if so, will the World of Warcraft community latch onto that, or will it be an entirely new audience?
