Blizzard Closes North Offices

An anonymous reader writes "GameSpot reports that Blizzard, the company responsible for StarCraft, Diablo, and most recently World of Warcraft, will be closing the offices of Blizzard North, the division of the company that traditionally housed Diablo series development. The article mentions that employees will either be offered severance or moved down to the Blizzard HQ to work on an unnamed project, and speculates that Diablo 3 could be the project. Is it just coincidence that Blizzard released the 1.11 patch for Diablo II on August 1st and closed the studio on the same day?"
