Gainax studio is no stranger at the San Jose anime convention, FanimeCon. Gainax's Executive Director and Co-Founder, Hiroyuki Yamaga has made almost yearly appearances since the convention began. What's interesting is that for the first time on Fanime's official dealer's list, Gainax is listed as having a booth. Currently it is uncertain as to what they will be using the booth for, though we're hoping it will be used to sell exclusive Gainax merchandise and goods from Japan.
Update: FanimeCon has removed Gainax from their dealer's list. A moderator on the official Fanime boards has stated that the company will not be holding a booth. Thanks to jimsha for the information.
