This BigDownload article has Blizzard CEO Mike Morhaime saying that the company's next MMO won't be a World of Warcraft sequel.
"It's not going to be a World of Warcraft sequel." he said. "So let's just say it's going to be different and it's not going to be a sequel to World of Warcraft. It will be different. We're not trying to replace World of Warcraft with this new MMO. We're trying to create a different massively multiplayer experience, and hopefully World of Warcraft will still be going strong when that one is released."
