From the post:
Chris Hartgraves from WasteLandsGaming.com, former employee of Blizzard Entertainment, has sent us word that Diablo 3 will be aired at Blizzcon.This would be an excellent change of events for anyone looking for the next great MMO. Honestly, Blizzard has the key to a great franchise that focuses on some fast and furious hack'n'slash. I have some other thoughts I'll be typing up at a later time, but busy business to handle right now.
From what we've heard Diablo 3 is going to be an MMO, as massive as World of Warcraft, with the concept of Hell invading Heaven. One rumor going around with Diablo 3 is that there will be Guild Housing included. The game is said to be looking brilliant and will be showcased at Blizzcon as their big surprise.
