Yeah, I think Sideshow knows we want a ROTJ Palpy (with lightnin' hands!) They also know we want his throne. It's also probably safe to say they know we want a ROTJ Vader (with unmasked headsculpt! with battle-damage hand! with wrap-around lightning! with funeral pyre!). Who doesn't think they're not planning on at least 2 versions of the Royal Guards (as in Crimson Empire)? They can't blow their load as fast as Kenner/Hasbro. Nor can many of us afford it. Patience...
By the way, ever wonder why Vader got so dusty after Luke wailed on him at the end of ROTJ? the floor of the incomplete Death Star's Throne Room couldn't be THAT dirty. The Special edition should have some added "Pardon Our Dust" signs.
One last thing, Sideshow, I DO want you to make figures of the Emperor's advisors. You had a 3-pack of Endor Rebel nobodies, and as well as you sculpt creepy old men, this set will be a sales win.
