It's interesting to see this bumped back up with a Hobbit line coming later this year and a new Star Trek movie in production.
I was watching part of the 2009 ST movie on TV last weekend and wishing that Playmates had done a better job on their toys. They had some good ideas, but the execution just wasn't there.
There have been several toy lines the last couple of years that I wish had been better; Pirates of the Caribbean, Tron (although that had some good stuff in it), Prince of Persia, A-Team, Avatar, Green Lantern...maybe one or two more I'm not thinking of. Those lines had some decent stuff, vehicles from Avatar and Tron, okay role play (Tron, PotC) and likenesses (A-Team, PotC, PoP), but none had the whole package.
One thing I did like was the Hot Wheels Star Trek ships from 2009 and I'd love to see a line for a bunch of different shows and movies get that treatment. A "Ships of the Future" line where we'd see stuff from Trek, Babylon 5, Stargate, Aliens...basically any property with cool starships.
