The Blizzard Announcement Tonight

[Bodhesatva]

Diablo III is unlikely. I'm not sure how well versed you are in Blizzard's history, but they were purchased by Vivendi 4 years ago. At that time, many developers left the company, most of whom were from Blizzard North, developers of Diablo.

In other words, Blizzard had two core development groups: the guys responsible for Warcraft, and the guys responsible for Diablo. They still have most of the Warcraft guys, but many of the Diablo ones have moved on.
