I got my HasbroPulse The Armorer exclusive today in the mail. This figure is all kinds of awesome.
It looks like the main differences between the standard release and the exclusive version is a soft goods fur cape (vs. a molded plastic), and four extra accessories for smithing. The extra accessories are a hot version of the hammer and tongs, a fire blast effect, and a Mandalorian Helmet. The helmet is cool to have in the tongs, but the other three accessories are just kind of meh.
I would say the soft goods cape alone is probably worth the extra few dollars and looks fantastic. This is definitely the way.
