Sideshow's Priority Pre-Order event for their Exclusive Boba Fett 12-inch Figure will take place this Friday, September 16th 2011 at 1:00PM ET. This exclusive version will include a 12-inch figure display base featuring the Mandalorian Clan Symbol, and it will be priced at $174.99 each.
I'm guessing that the Exclusive Boba Fett will sell out quickly, but - luckily for collectors - that amazing light-up base (shown below) isn't the exclusive item...it will come with the regular run figures as well.
