Wow, lotsa speculation...
I gotta disagree in that I would NOT be happy with a re-release of the Saga Snowtrooper. That figure wasn't much of an evolutionary step forwards over his POTF2 counterpart. The sculpt was slightly more crisp, and he did have a holster, but his articulation they added was pretty much useless, and he had a wonky pose. He's a rough looking army builder, most noticeable when there's 2 of him together. They just don't look right... Not to mention he does sport the officer's bars too, which are small details but still one more thing making him less than ideal army builder fodder.
I'm of the opinion that anything in Imperial/Clone armor should be done a-new with the super articulation treatment. Snowtroopers and Scout Troopers are on top of that list for me though, as a classic film fan (plus repaints of prequal Clones are easily doable for both sculpts), but also because I think that both those "characters" have gotten the shaft.
The POTJ Scout simply blows... His goofy pose, his lacking articulation, his pinhead... He blows. And the Snowtrooper's POTF2 incarnation is at least neutrally sculpted, but he and the Saga figure are both sub-par.
I'm not expecting it, but my ideal Hoth wave (if they're only in 3's) would be:
-Major Derlin (Toryn Farr a close runner-up though)
-Super Articulated Hoth Rebel... Like the Snowtrooper, the Rebel figures have all sucked terribly. The only one close to ok has been the Deluxe one and he's weak these days. Gimme an all-new figure here, tons of articulation, proper scale, softgoods scarf... I'd dig it.
-Super Articulated Snowtrooper... Softgoods mask and skirt. I'd be broke if this guy came out. I'd have to live off raimen noodle soup just to afford my army.
Others I'd like... Veers w/removable armor, hat, helmet, and belt. Torryn Farr (like mentioned). NEW Hoth Han Solo (good articulation and pose, removable hood/hat). Brown Vested Rebel Officer (Vintage resculpt). Snowspeeder Luke. Snowspeeder Wedge. Snowspeeder Dak. Snowspeeder Hobbie. Snowspeeder Zev. (Hell, do one figure, then just do a pack of the Snowspeeder pilots called the Rogue Squadron Battle Pack
Figures I know I DON'T want though?
Hoth Vader, Hoth Chewie, Probot, an astromech (with the EE packs, I'm ok on these for a while), or a repackage of any of the figures I listed that I do want.
