To go with something JACK touched on, I think the argument that characters like Vader not being a Vintage figure isn't a good one. He has sold decently. At least near me he has, and I wager if you asked Hasbro they'd say he's selling well on any card. Other characters tend to do well like that too.
But like JACK mentioned, those figures subsidize the obscure... It's a fact of life you're going to get them.
However, I do agree with you Steve that some of those should probably have been relegated to either Legacy, or Vintage, but certainly not both. Obi-Wan for sure, Anakin...
But then that leaves Hasbro in a dilemma, where they release them on Legacy cards where they're the better value ultimately, but then they're ignoring the collecting world who maybe want the "main" characters to turn up on Vintage style cards. Ani/Obi on vintage cards in a ROTS wave are figures I only buy if there's something new to them, but some folks would not be happy if ANi/Obi didn't turn up on vintage-style ROTS cards because they're the main guys.
But I totally agree that there have been too many Legacy/Vintage run-ins with figure choices, and it's not helped. It certainly hasn't helped the potential kid purchases from parents/grandparents, as Legacy's the better deal.
JACK listed a lot of great collector-focused stuff though. The line's definitely doing a lot for the adult collectors then. They're never going to be perfect on the basic line's choices, but I think they're doing ok. I wish they'd maybe limit the number of certain figures like Obi-Wan, if they're putting out a repack on the vintage style cards. Then again, Hasbro probably thought the Clone from ROTS was a great idea. Now it's languishing on the pegs everywhere. Sometimes I suppose it's a crapshoot as to what people will or won't support.
To add to the point about Legacy/Legends though, I have to say this line was abandoned almost completely for collectors. That is a bummer. I really enjoyed 2007, though it was expensive collecting repacks and the new figures at the same time. I'd like to see them be a little more conservative about what they do with Legends then, instead. But it's the only way figures like Jocasta Nu will ever happen too, so it's a necessary evil.
