I read something a while ago about Richard A Knaak saying that blizzard is using the Sin War trilogy as a storyline for something. He wouldn't say what but at the time the site was speculating about a possible movie. I think it is very possible that the story line for D3 will be in the past rather than a sequel to D2 LOD. I can't remember but are there actually more than 3 prime evils or is it just diablo, baal, and mephisto. I'm probably confusing something else I read about 7 prime evils but I can't remember honestly.

I suppose we will just have to wait for blizz con like we had to wait for the Korea Announcement for SC2. In the mean time I will dwell on Warhammer... lol.
