They're actually in Irvine, which is not Anaheim but still WAY closer than San Diego. The layout of the Anaheim Convention Center is way better than San Diego in my opinion and I really like the fact that they keep it in Anaheim.

I live about 10 minutes away from the Anaheim Convention Center and get a hotel next to it every year for BlizzCon. I wouldn't mind driving to San Diego for BlizzCon and doing the same thing (I did it for ComicCon) if there were some benefit to it, but I don't believe there is.

San Diego is great for non-centralized conventions like ComicCon because every vendor, exhibitor, etc... is doing their own thing. At BlizzCon these are either Blizzard or companies that make stuff based on Blizzard franchises and the layout of the Anaheim Convention Center keeps everything really easy to access. It's literally a straight line walk from one end of the Convention Center to the other. It's great.

Cheers, Blizzard. I look forward to wasting another day at work when the tickets go on sale. I spent (literally) all day last year buying tickets to go and plan to do the same thing this year if I have to. Hopefully things will return to the way they were in 2007 where I had tickets within minutes of them going on sale, instead of nearly 8 hours later like last year.
