that actually makes sense, I wonder why the the battle chest containing all 3 isn't on the list tho

This is old, and completely rumor.  There's nothign offical about this release list, and if you look at it there really isn't a good reason to believe it.  SC2 Exp 1 in the same quarter as a spin-off AND Diablo 3?  WoW expansions faster than ever, Diablo expansions just as fast, SC2 expansions faster than that?  Titan, an MMOFPS, releasing in the same quarter as a WoW epansion?  Way too hard to believe.

well as has been discussed phoenix probably isn't a game, SC2 and Cataclysm came out in the same quarter, if you look at Burning Crusade (2007) Wrath of the Lich King (2008) Cataclysm (2010) expansion 4 in 2012 seems perfectly in normal for wow exps, a bit of perspective brood war came out the same year as Starcraft 1, the frozen throne came out 1 year after WC3 and lord of destruction came out one year after Diablo 2 as for the last point see my first...
