As far as prequel figs I'd be all for that...but not at the 100% markup. I've been asking for new Super Maul, Qui-Gon, Obi-Wans, Anakins and Dookus for a while now (with little support :p) It's something I want to see happen though
Hey, don't forget that I've been calling for those too. I think the Jedi and Sith really do need to be presented in a manner much like the VOTC in terms of sculpting and articulation. If Hasbro would present these ultimate versions, and not something like "Coruscant Chase Obi-Wan & Outlander Obi-Wan & Arena Obi-Wan & Pilot Obi-Wan", I would gladly fork over $10 each to save myself the $20 that four basic versions would cost.
As for the VOTC line, I'd like to see it continue with characters that were part of the vintage line. The 12 back characters would be a great place to start.
