I guess I'll be selling that kidney to get the RH Vader after all. 
I wouldn't quite yet, Michael. Hasbro's gonna be dumping a few more of these Unleashed rehashes, I think, and they're well aware (or at least I made them well aware at SDCC) that they definitely chose the wrong Vader to re-release, as the RH version is much rarer and tougher for collectors to acquire. They seemed to realize that, I suggested not to give up hope yet, as more rehashes may be coming down the pipeline a bit later on. But yeah, based on how bad these four (three, probably, since Fett will move) are gonna stagnate on the shelves, it'd be a far stretch of the imagination to think Target or WM would be going for any more of these Unleashed exclusives, especially considering how much shelf/retail space they take up in those fancy new cylindrical packages.
But who knows, maybe TRU has got one or two lined up as well... Yoda, Stormtrooper and Padme all come to mind as possibilities as well. But I'd definitely prefer to see that RH Vader make it into the mix, as that's the last OT one I still need.
