Blizzard Needs to Make Something New

One of the editors at the Minnesota Game Examiner has penned an article that pleads with Blizzard to develop a new franchise rather than rehashing the same three over and over again.
Besides those aformentioned two games in '95, in fifteen years they've made fourteen games, sequels, and expansions, and they have four more under development. That means that they can account for eighteen games, and I'll bet anything that Diablo III will probably have an expansion; WoW hasn't hit 99 level cap yet (if indeed they plan to stop), so they'll do another one too. Oh, and there will probably be a World of Starcraft sometime in the future also.

The point in this?

Blizzard needs to try something new. Something original. It is very clear that they have a crew of talented writers who can summon up droves of interesting and compelling storylines. They could easily start putting together concepts and people to start a new, original idea. Yes, with the amount of money they make it's clearly and entirely unnecessary for them to ever do anything differently.
To be fair, there is such an extended delay between each of Blizzard's releases that it's almost as if they're "reimagining" them each time. But I suppose I wouldn't complain if they started development on a brand new traditional RPG :).
