Blizzard just announced their newest upcoming game,
Diablo 3, during the opening ceremony at the Blizzard World Wide Invitational '08 in Paris France. Keep your eyes open on all your favourite sites for more details as the sites get their feeds out.
Cladhaire is at WWi and will hopefully get a chance to play it while there and give us some feedback on it when he gets home, so watch for that as well.
You can download their game play trailer
