Personally on an expensive figure like this, if they can justify lights anywhere, it's the chest and belt. Although I'm a sucker in general for extra accessories and lights, I'd be fine if they skipped the light-up base and helmet/stand (one can make a pretty strong case for a reveal HS with a Jedi Vader, obviously -- even if not at all close to Shaw).
Gotta disagree about the sabre unless Sideshow went all out and did cold cathode. I'm guessing if SSC or HT ever get into making CC sabres that they could perfect them and get away from any wonky end-bits and really make them look perfect. Until then, I'd prefer to stick to after-market. The sabre that came with Padawan Obi-Wan was horrible and hopefully SSC never attempts to repeat it.
