I was just thinking about Rebel Pilots last night, and I don't disagree. I like 'em, but I'm good unless I have a pilot seat to fill or there is a new manufacturing technique. At this point there's nobody in the flight suits that I can say I specifically have been wanting in 3 3/4-inch - I mean, Hasbro nailed it. Griz Frix? Shira Brie? Cesi Eiriss? Wedge after Wedge? Biggs a-go-go? We've done well here. Heck, I'd go as far as to say I'm good for Imperials - minus a couple of retro updates, maybe - until we have some big ships or playsets to fill out. Even Ewoks, I can't believe we've got Marvel-based Ewoks - maybe some Kenner flavor ones, and a realistic Cartoon Logray might be fun, but that's where I'm at. We really got a ton of awesome stuff over the years.
I think the one area there is still some need on your list is Imperials...not sure how well the sets would sell but I think updates to Ozzel, Piett, Veers, and especially Tarkin with some holes in Sheckil and Lennox and there could be enough there. Would people buy it?
I also still really hope you can get that Funeral Pyre Vader set made, that thing was awesome (now with bonus Kylo Ren holding a mini Charred Head)
