Great answers B'Omarr and JediMarvin! This was the kind of discussion I was looking for. I get alarmed myself when Hasbro will be releasing 40 more figures this year (thereabouts) and I'm only planning to buy 5 of them. My purchasing tastes are a lot like the way B'Omarr described his. I'm not after the recardings, and I'd have to have or create a need in a diorama for me to pick up a resculpt.
Part of the history in the hobby for me was finding my first modern POTF2 Star Wars figures at a Trek convention in September of 1995. I remember the glory I felt that day, and consequently I'm not embarassed or even remotely considering replacing my "He-Man" Luke Skywalker figure with the long saber from 1995 that I use in my rope-bridge swing, Millennium Falcon, and Mos Eisley cantina scenes. Perhaps his body doesn't look authentic to the movie, but his face sculpt and his realism as a human character still fits right in alongside Bo'Shek and DjasPuhr and other more recent figures. Cantina scene Ben Kenobi's there, too - as I don't detest that figure and in my scene his pre-pose works - and that's how I got my Dr. Evezan figure in the first place.
So the answer is "No," I'm not looking to replace any of those figures with new and improved versions. I just hope that either there are enough new collectors or people who will still buy the recards and resculptings that the hobby will continue so I may add Hem Dazon and a Gotal to my bar scene and it's far from the last thing I do.
Anyway, Finish Voting Best Prequel and Sequel figures:
(JediMarvin, you too, if you care to)
Padme Handmaiden or Cliegg Lars???
Black Bespin Guard
