Darren recently made a post about AoC vs WoW, discussing what Blizzard should/needs to do to maintain their large customer base. I agree with him and several others that Blizzard will barely even feel the bump caused by AoC, and they really have nothing to worry about. In the comments of Darren's post, people had brought up Diablo 3 as a potential customer "bringer-backer-inner".

I myself, do not play WoW or currently any games by Blizzard, just because i've worn out Diablo 2 over and over again, and as many times as I've tried, i just can't stand WoW. Were Blizzard to release Diablo 3 (which hasn't even been confirmed yet) I can safely say I would end up snatching it up on release day, and probabally even need to call in to work for a couple days. Now if they made Diablo 3 an MMO I'm not too sure how well that would work with Mythos already out there. I would still pick it up none-the-less and enjoy it as much as possible, that is for sure.

In closing, I never thought i'd be excited and anticipating a Blizzcon (barf) but, i actually am, just to see if they say anything about Diablo 3.
