Unconfirmed: Two Diablo III Expansions and Two More WoW Expansions Planned

It appears that Blizzard Entertainment's planned product schedule may have been leaked into the wild, and assuming it isn't a fake, the schedule lists Diablo III for "Q4 2011", a "Diablo 3 X1" for Q2 2013, a "Diablo 3 X2" for Q4 2014, a "WoW X4" for Q2 2012, and a "WoW X5" for Q4 2013. Some StarCraft II entries and a listing for "Titan" also appear on the schedule, the latter of which we can only assume refers to the company's next as-of-yet unannounced MMORPG.

Unconfirmed? Yes. Unlikely? No.
