I have actually gotten a complete set of the silver figures, and just like I predicted, they look really nice together... I'm not a carded guy, but these in a set are a neat centerpiece to an otherwise loose collection IMO.
I'd like them to do a 3PO, and then can the line... The Sandtrooper and 2nd Vader were wastes IMO. The Sandie could've been a basic Stormie I think, and would've made more sense... not sure what the thinking was on using the Sandtrooper.
I'd almost take an Emperor... A 3PO should've been in place of the 2nd Vader though. I almost think they're doing this other Vader as an "apology" for the first Vader, but to me this is one of those series that you shouldn't produce to appease people... I can see producing ENOUGH of a figure to make people happy, but not producing NEW figures to apologize for shorting a previous one.
