Please NOT another Luke or Leia we have enough of them. 
We have too many craptastic Luke figures, I'll agree. But as my comrade
Spuffy (Hi Spuffy!) points out, there are still plenty of Luke figures than can be offered. And as long as retailers insist on main characters in their assortments, we'll just have to live with them.
Personally I'd rather see Hasbro reissue decent figures, but there are plenty of POTF2 era sculpts that still need the POTJ treatment. Don't get me wrong, I don't want a steady stream of new Luke figures from now 'til 2018. I want never-before-done characters as well. But I think there's a balance that can and should be achieved.
Heck, if Hasbro can offer Bacta Tank Luke, a Medical Frigate version is probably not far behind. (Even another Tatooine Luke WITH PONCHO, though it'd be the last one I'D ever want to see.)
