Lots of choices with this wave as well. There are many new characters/new sculpts I'd like to see personally, but being realistic, probably half of the wave will be new, the other half old. I'm hoping if we do see a 1 per case scenario like Jeff mentioned, the repacks are the 1 per case ones. That would make sense, but we'll see. Anyways, here's some I wouldn't mind seeing:
SA Snowtrooper - I wasn't happy with the Saga one in particular either. Nice enough sculpt, but the figure overall could be much better.
SA Hoth Rebel Soldier - This figure really needs to be redone I think, the Saga one was craptastic.
Major Derlin - Very nice choice for a "new" figure that we haven't seen before, and I think we'd all be happy seeing it in the line.
New Snowspeeder Pilot Luke Skywalker - A figure I'd really like to see, they could do a nice job with this if they did an all new sculpt.
SA New Sculpt Han Solo Hoth - Probably not likely, and maybe not all that wanted by the majority of people. The Saga one isn't awful to me, but could be much better. Maybe not the top choice right now, but I wouldn't mind seeing this figure re-made eventually.
2-1B - Repack is fine, although I wouldn't mind a new one either. I never got the POTF2 version, and have been waiting for a resculpt/repack of this one.
Hoth Luke Skywalker - Repack from Saga. Pretty good figure overall, maybe a bit underarticulated, but otherwise a nice figure I think.
AT-AT Driver - Repack or new sculpt. Haven't seen one in the line for quite some time, another figure that I don't personally have. I don't know what the opinions are of the POTF2 version, but if its good, a repack is fine.
There's just a lot of options for this wave, much like the Endor one. Veers, Torryn Farr, and many others could be good choices as well.
