Yeah I dunno how they're going to manage that with the HoTS beta starting to generate some serious steam and SC2 expansion due out soon (god damn it I need closure on that anecdote), plus another D3 expansion in about a year or so, and of course WoW being WoW. Probably another Hearthstone expansion in 2015 some time too. Lot of balls to juggle. Suspect it might be pushed out to mid to late 2015.
Wonder if there'll be a technical alpha this time.
