What many don't realise is that Diablo III's release date is likely closely tied to the release of StarCraft 2.
That does unfortunately NOT mean it will be released at the same time or even right after. All it means it's part of Blizzard's internal release schedules (yes, they most likely have them, they just don't pay that much attention to them), and that relates to StarCraft 2.

Diablo III Season 38 launched with Ethereals back, but players are reporting Error 395002, disconnects, and server trouble.

Diablo 3 Season 38 starts March 27. Here’s what to finish before Ethereal Memory begins, from class choice and stash cleanup to Conquests and Ethereal

Via Diablo’s global director of community Adam Fletcher, Blizzard is introducing new measures to improve the quality of season launches in the future. Across both Diablo 4 and the aging Diablo 3, fans of Blizzard’s games should all benefit.
If they didn't let the cellphone guy touch the 3rd one in first place, they wouldn't have to dance around like clowns trying to make money.
We've been asking for less "boring" seasons... "boring"... not "buggy"... same ol' rehashed content just a different color is not working.

Late 2011!
Since they kept pushing SC2 back, I wouldn't be surprised if D3 isn't too far behind - but it will be interesting (with the 2 SC2 expansions lined up) to see how they handle the releases.
Yeah a year after sounds right
I'd agree that it's probably going to be released at the end of 2011, but blizzard probably have their hands completely full since announcing that sc2 will be split into 3 games.
