Blizzard has been riding the gravy train that is World of Warcraft for some time, much to the dismay of die-hard Diablo and Starcraft fans. Something new is in the works, however, and supposedly we'll hear some good news from the company in a few weeks. While they aren't releasing specifics (though we certainly hope it isn't another WoW expansion), they have stated they will announce a new title next month in Korea:

"We do intend to announce a new product at the Worldwide Invitational next month in Korea, and we appreciate the enthusiasm and interest in getting an advance look at what that will be, but players will have to wait until May 19th to find out more," read a statement that a Blizzard representative provided to DailyTech.
It could be the next iteration of Starcraft or Diablo, or perhaps a new series altogether. Either way, Blizzard has proven themselves to be a quality developer and I'm eager to see what they have in store.
