I don't know how to get one of these at SDCC but I'm probably going to race to the Lego booth first chance I get. I really want this in my collection.
You have to line up outside in the back at the "pavilion." They will be handing out tickets this year. People line up the night before for the hasbro tickets, so not sure how bad this will be.
