I do the same as well! Organizing them any other way wouldn't feel right for me.As someone who organizes shelves by movie, I’m very excited for TESB Vader- if just for completion’s sake. ROTJ and ANH already have theirs, so it’ll be great to complete the OT Vaders (with the exception of Cave of Evil Vader).
Do we know that it doesn't? Hasbro has been known to surprise us...from time to time. Look at Zorri Bliss for instance.I do wish the top of his helmet removed to work for the meditation chamber scene. Though if we were ever to get that as a set piece I'm sure they'd sell us another Vader with it anyway.
