Quite a few i like Vader vs Ben, Vader vs Luke ESB and Meditation Chamber Vader.
Voted for Vader vs Luke DS2, one of my favorite parts of the saga and the Emperor sitting in his throne watching would be a must.
I voted for Vader vs. Obi-Wan but really I want Luke vs. Vader on Bespin and Vader vs. Luke ont he Death Star II as well, the exact order they come in doesn't matter much to me. Excpet I want the cheaper ones to be done first. For the ROTJ I really want Luke and Vader with their sabers crossed in front of the Emperor as he sits on his throne. Also I hope that for Bespin they eventually do two. One where Luke and Vader are actually dueling and the "I am your father" scene. Personally I only want the first to keep the motif of having the major lightsaber battle from each film, but the second is to iconic to not be done and I fear they may do it over the actually duel.
I would be seriously tempted to get a Yoda vs. Sidious and Ani & Obi vs. Dooku on Geonosis since I consider those to be the other half of the major duels in AOTC and ROTS.
My vote went with ESB, though I have to say, if I thought the ROTJ duel would have the Emperor sitting in his chair as well, I'd happily render my vote unto that.
I'm hoping that if Sideshow doesn't already have it in production enough people wanting Palpatine in the ROTJ duel will sway sideshow that way (if they aren't thinking it already).
Anyone have any idea on how long it takes from the time one of te polls come up and when they debut the one already in progress?
