I don't think this has been posted yet, so I'll go ahead see what you guys think.
I found an interesting article from the San Diego UT newspaper. The article was posted July 17th, a few weeks ago, and is about SDCC and the rent price decrease that the convention got for the next few years, but the writer also mentions Wondercon. In it he interviewed Jay Burruess from the Orange County Vistor and Convention Bureau and claims that Wondercon is returning to Anaheim again next year. While I wouldn't take that as anything offical, I think it's interesting and could be a little telling. But anything can happen and Ill wait for an offical statement from CCI
