If we're talking about what we want repacked into another line (IE: Saga 2006), then here's what I'd dig:
-Royal Guards (Blue & Red)... To me these are repack fodder for years to come. Make a third one with the open-faced TPM helmet and I'm game for that too. A nice pike accessory would help as well.
-C-3PO... Though I agree with Jeff I'd rather see a SA 3PO, or at least one with joints at the bicep, wrists, and hinged knees. SA's tough on 3PO, but when I was reviewing the figure I noticed that the sockets they used for his pull-apart feature could easily be applied to working knee joints, and swivels at the bottom of his shoulder plate/top bicep plate, and his wrists. They can do better.
That said though, a 3PO ROTS re-release with a silver shin would be an ok re-release... They're far from perfection on this guy though.
-Wookiee Warrior... I agree with a re-release of him CHEWIE, actually, so I gotta go against you on that one Jeff.
I'd like multiple colors of the Preview Wookiee actually... A black one with brown stripes would rock, as would a cream one... Head variations would be nice too.
I don't want that other Wookiee re-released though. I despise that figure, and wish they'd resculpt a "normal" sized Wookiee for the line that was at least as poseable as the Preview. Then again I think they should resculpt Tarrful as well so he's more poseable. Hasbro dropped the ball bigtime with the ROTS Wookiees.
-AT-TE Gunner... Give him some flavors even. Most people use him as a grunt I figure, so may as well make him in Utapau, Coruscant, and 501st colors... I'd take EU colors too. He's just a good figure and adds some diversity to the ranks.
-#41 and #6 Clones... I know not all will agree with my opinion of the #6 being re-released, but I liked it, and it's the Clone I can get to kneel better than any other for prone poses. Again, release them in all the film colors, and add in some EU colors too and I'm a happy camper, though I agree that whites are good too (I wouldn't release the #6 in white however, just the SA one).
And as a little addition... They should be releasing SA Episode 2 Clones in white as well. Why they don't, I don't know. SA Stormtrooper (VOTC and the Evolutions Sandtrooper) should also be making their routine rounds on the pegs. Hasbro needs to just **** or get off the pot on this one though.
Those are the figures I currently would like re-released across different lines...
If we're talking just stuff released within the ROTS line that's currently running though?
I'd like to see a SLIGHT re-release (IE: Don't flood the pegs) of a lot of different figures/characters.
-Clones (Of course)
Those are probably the top ones I'd like to see a re-release on though... I know I've been trying to track a Mace down for the boys but I can't find one.
Isn't most of that stuff getting mixed into later assortments though I figure?
