I'd much prefer a 3-pack of 3 of the same Super Articulated soldier than 3 pre-posed ones...
That's what I'm hoping for with the army builder sets more than anything, but it's not what I'm going to count on. pre-posed 3-packs are remotely interesting, but going to still disappoint me compared to a super articulated army builder. Pre-posed just doesn't = action figures to me, no matter how decent they look in a diorama.
The fun just isn't there.
For the Cantina 3-packs, I'm hoping for about the same thing you are Scott, but not going to count on it... Only the 3 like Ktik and crew are the ones I'm counting on... The other pack, sadly, I think will be repacks.
Here's my hope for the army builder set...
-Imperial: 1 SA Stormtrooper... 1 SA Snowtrooper... 1 SA Death Star Trooper... (This would be a dream come true for me).
-Rebel: 1 SA Fleet Trooper... 1 SA Hoth Rebel Soldier... 1 SA Endor Solder (Or Rebel Tech, or Honor Guard, or Snowspeeder Pilot).
Well, wishful thinking of course, and not likely, but it'd be nice... I'd take 3-packs of SA Clones over the pre-posed ones we got any day though, and same would go for the classic trilogy.

For the other things, I'm mixed...
I mean, on the cases, I don't care really, but if they have decent figures I'm all into it. The playsets I truly am hoping are NEW, not those craptacular little tiny sets from some years ago. Those things were horrible I thought, and waited till I saw them for under $5 to pick them up (took a while, but eventually people dropped the price looooow).
The vehicles disinterested me as well... I know others are into a Sandcrawler and Y-Wing, but I just can't get excited over these two. I don't feel the old molds do either vehicle much justice (and I'd never expect a to-scale Sandcrawler!)...
I'd have dug news on a cloud car, though I think it's only time for that. The Hasbro pilot figure is shaping up to be a daisy, so I can't wait to nab a car for him to buzz around Bespin in.
So, Swami's news is something that COULD be great, but I'm not getting my hopes up much. Especially on the 3-packs really. I'd love to see something really special done with all the 3-packs though. We can always hope, and think of what COULD be anyway.
