You guys are taking that chart too literally... does no one see the bold disclaimer at the bottom of it? Someone may have just made that according to past release dates.
I fear when I get home my roommate's poor kitty has already been sacrificed..
The disclaimer was added by MMO-Champion. The chart has Titan's actual codename (before it was public knowledge) as well as WoW TCG aka Hearthstone, and the provenance of it was a Blizzard China employee, Ye Weilun, sold it and lots of other confidential Blizzard data to rival companies, and an employee at one of those companies that bought it leaked it on a Chinese forum. http://news.mmogamesite.com/blizzard-china-manager-resigns-management-reshuffle-for-leak.html
An interview with Jay Wilson also 'confirms' multiple expansions. "There's a lot of people on our team who aren't happy with our class choices,” Jay admitted. "But after we've established 'Diablo III' as its own game with its own type of gameplay and experiences, I wouldn't be opposed to looking at old classes. We are trying to design the Witch Doctor class so that if we did bring back the Necromancer, there's room for him. We're looking out ahead of time at what our expansions are going to be, so we've got to keep room open for some of those other classes down the road."
