The Ryloth episodes... Weren't these the guys at the head of the armored column? Or maybe I'm misremembering that. There were a number of AT-RT's on Ryloth as I recall, but that's an interesting deco on that one... buzz = instant pegwarmer, haha. But the AT-RT, maybe not. I like weird paintjobs so I may nab that.
BTW Hasbro didn't talk a lot about exclusives at Toy Fair... i think in general they don't because it's less for collector sites, more for retailers, and the exclusives are locked up. Images of those turning up implies they're not too far off. Month, maybe two I'd think.
