Saw Guru revealed at some point that they not only could make the revealed figures of Aquaman, Ice, Superboy, & Damian Wayne . . . but they also happened to have a 5th never before seen figure that had been in the works or that they were able to afford to release.
If the choice for you is a repaint like light blue Superman, fine say that . . . but also include a "never done" character or look (ex: 80s Nightwing is a valid want).
You'd break it down like this:
1) Complete Personal Want:
2) Works well based on what's been made and what is needed but not necessarily what you personally want most (ex: Getting Kyle Rayner Green Lantern to go with the Morrison JLA).
3) What you could see being made based on tooling issues, trends in selection process, and the closet theory (as I call it, where Mattel is cleaning out their closet of figures made years ago).
My personal choices:
1) Ravager (though I admit I am not so crazy for her since she wouldn't have much of her team)
2) Green Lantern (Kyle Rayner)
3) Vixen
