Cosplay Girls, San Diego Comic-Con 2011, California, United States

Heidi McDonald reported on her blog The Beat as of October 7, 2009 Preview Night for the 2010 show has already sold out. Glazner explained the early sell-out:
For 2010 the decision was made to offer an option (of whether they wanted to attend Preview Night) to those who pre-registered for four-day badges. We limited the number of badges for Preview Night to the number of those who attended in 2008.
Mark Evanier on his blog News from ME noted as of November 9, 2009 all 4-day passes for the 2010 show had already been sold out. On February 23, 2010, The Orange County Register reported that the larger Anaheim Convention Center in Anaheim would be making a bid to become the new home of Comic-Con starting in 2013. On September 30, 2010 Comic Con announced that they have extended their stay up to 2015. The North County Times reported on July 26, 2010 that 4-day passes with access to Preview night for the 2011 Convention sold out two hours before the 2010 convention closed. Due to overcrowding organizers of the event capped attendance; this cap has been in place since 2007.
As of November 2012, there is a $520 million proposed expansion to the San Diego Convention Center. The proposed expansion would increase the available space within the convention center by 33 percent and has a target completion date of early 2016. Due to the proposed expansion of the convention center, Comic Con extended its contract for San Diego to 2016.
