MMO Champion has what is probably the best analysis of this. Unsurprisingly, Activision Blizzard is in full license molestation mode.
Note no sign of the long rumored “new next-gen MMO property” Blizzard has been hiring for for a while now, unless it’s the “Titan” entry at the bottom – and a Q4 2013 release for a WoW-scale MMO is, to put it mildly, unlikely.
Other then that, no real surprises: Blizzard is preparing to turn Battle.net into a digital DLC distribution portal and eventual Steam competitor (apparently the whole turning it into Facebook thing didn’t quite work out), Diablo 3 and the first Starcraft 2 expansion pack are both due out late next year, and World of Warcraft will have expansion packs slammed into it, starting in 2012, on a yearly basis.
Still, this chart is very handy for every other gaming company on the planet to schedule when NOT to plan their MMO releases.
