Well, my Vintage line collecting has stayed pretty focused to only collecting those that have actual vintage origins and so I'm pretty excited for any upcoming figure that further completes the count for those. However, there are non-vintage line characters that I've been dabbling in since they've been too good to pass up, and in that regard I'm really looking forward to Tarkin and Dr. Evazan. Especially Tarkin since I find it amusing. I KNEW they were full of it back in '06 when they said the ROTS Tarkin would be the last new Tarkin ever. ...I just had to wait 6 years to be proven right...
The only original-vintage figure that's getting a new release on vintage cardback that I'm a bit iffy on is the Emperor's Royal Guard. It looks great and all, but I feel it's ridiculous that they continue to fail to give him a hand to properly hold the pike. Just include a hand with a cupped grasp and call it a day! The POTF2 version was the last one that could hold the pike in anything resembling a natural pose. On the opposite side, though, I am most looking forward to Weequay since he was one of my favorite figures back in his debut year and I've been waiting for a new version of him for a long time.
As for what I feel is left to be made... well, I want any figure that was originally released on a cardback in the vintage line, including new versions of both black AND white Bespin Guards with their own unique cardbacks. Though, of those, the one I would be most excited for is Han in Carbonite. There's been some very cool reveals in the replica community with details of the Carbonite block in the past couple of years and I would like to see Hasbro make one that's as accurate as possible. I think they could do a very good job with it if they do their homework.
As for non-vintage originals, well I would really, really, really like to see a new Dash Rendar as well as Leebo and Guri finally made as figures. But, most of all, figures from Dark Forces/Dark Forces 2. I swear I could retire from collecting if they made the DF2 Dark Jedi characters and 8t88.
'Course, it would be my luck that they would make a whole wave of just Dark Forces figures, but it would be the last of the vintage line and they'd all become exclusive to ebay. I still have yet to get the phase 1 or phase 3 versions of the Dark Trooper. -_-
