Just catching this thread...
I went down for Sat & Sun with my SE Fett. There appeared to be a number of Fetts floating around on Sunday. I also had a few people that wanted Black Series Fetts but they were well sold out by the time I arrived on Saturday. I worked the Hasbro booth for a couple hours though and word is that they'll be making it up to us. If anything I got some good laughs hanging with their full size Carbonite Han and doing my best Robot Chicken with him.
Fett is a complete hit at SDCC though. Daniel Logan came up to me for pix, Manny Pacquiao and his crew videotaped me faux boxing with him, and it doesn't suck to have Slave Leia's chasing YOU down for the photo op. Keep your momentum up and a wrangler near!
