Yeah, I'm rather curious about what happened to this figure as well. It better still be headed stateside at some point, since I really don't want to have to search this Clone down at a higher price on eBay or from an etailer, most likely out of the country.
To be honest, I'd rather Hasbro not have even made the Silver Clonetrooper, since it doesn't mesh well with the "Silver theme" that is/was ANH's 25th anniversary. To tie anything of a prequel nature in with something that should just be OT irritates me to no end.
But I'll pick one of these up regardless if/when they ever see the light of day here!
