I'll start off with some old news. First up...
Jeffrey "Tigole" Kaplan has left his position as Lead Game designer of World of Warcraft to instead work on Blizzard's upcomming, and currently unannounced, MMO. While he'll still be involved with the game, he'll leave the day to day operations to his collegues Tom Chilton and J. Allen Brack.
Good luck Tigole. I'm counting on you to work your magic on that new project of yours.
