Looks like San Diego Comic-Con is going to stay in San Diego through 2016, at least:
A $500 million expansion of the San Diego Convention Center has been authorized by San Diego officials, with San Diego Comic-Con extending its deal for an additional year through 2016, according to Variety. Construction will begin next year and will be completed in time for Comic-Con 2016. The expansion may finally allow Comic-Con to expand its attendance beyond the current 130,000, where it has been capped since 2007 because the Convention Center is maxed out even with the addition of off-site space for things like programming and premium redemption.
Because that’s what Comic-Con needed: More people.
