Tickets for Wondercon in Anaheim, California have offically gone on sale. Wondercon is set to take over the Anaheim Convention Center March 29-31. In order to purchase badges, one must have a Member ID. Although Wondercon tickets won't sell out or be nearly as coveted as SDCC badges, it seems as though Comic-Con is trying to move everything over to the new system by forcing all badge holders to have a Member ID.
There's no rush to buy tickets right this second, but the $40 early bird 3-day badge is a great offer. Although panels and special guests won't be announced for a month or so, check back for updates and rumors on Wondercon 2013.
