According to the Official Site, the exclusive Clonetrooper bust should definitely be there, but in very limited quantities (I think only 1,000), so just showing up will definitely not guarantee you getting one. Thing Jorg Sacul distribution at C2, but 30 times as hard.
I'm sure Hasbro will be at the show though - and might even have a new figure or two in tow, and there's likely to be lots of other Star Wars loot all over the place - dealers galore! I'm sure you'd have a great time, assuming it doesn't cost ya' an arm and a leg to get in! It's pretty much similar to the San Diego Comic Con, if you've heard anything about that...
