On the Clone issue, has anyone else noticed that the #41 Clone and the CW Clone are different sculpts in most areas? They've already done a ROTS style Clone head for the Target Clone, so why not put that sculpt to use, alongside the #41 Clone and the #6 Clone if they are that strapped for molds? Just a thought...
And for the rest of my post I'm going to pull a rabbit out of my hat. Or comment on Corran's list. Probably the latter.

Attackix
Failure. It might move in some areas, but it's bombing everywhere I go.
Unleashed 2"
Destined to fail. The figure sculpts don't have near the detail as the 7" line, and they look like less cartoony Attacktix.
Titanium
Bombing badly. Every WM I go into has an endcap *and* a section in the SW aisle, not to mention a small section in the die cast aisle crammed full of the 04/02/05 assortment. And Hasbro decides to get all the other retailers in on the disaster in the new year.
Target's Micro line
Not selling at all, hardly. The only thing I ever see move from these toys is (surprisingly) the Invisible Hand. And since Hasbro's already said this last ROTS assortment and the Turbo Tank is it for now, at least they're paying some attention.
Force Battlers
Complete and unmitigated disaster. Vader sold, as did Grievous after a long while, but Anakin and Obi-Wan are permanent fixtures on the pegs at this point, and in great numbers. But try getting Hasbro to admit the line is dying.
Potato Heads
Every Wal-Mart I go to is sitting on at least 60 of these. Target and K-Mart, while less clogged, have them sitting in the same position and in the same numbers every time I go in. Not a success at all, IMO.
Evolutions (figure sub line)
Although it's still too early to tell, I think this line is going to do very well. The Anakin set seems to be getting almost universal praise, the Clone set is highly anticipated (and will be a massive headache to find, I'm afraid) and the Sith set is giving us Ultimate versions of the three non-Vader Sith Lords. If they don't overship Anakin, and they ship the Clones in ridiculous numbers, this is going to probably be the best side line in the line's history, IMO.
Battle Packs (figure sub line)
Well, the Sith vs. Jedi set has only shown up at my local K-Mart and the same four sets have been sitting on the shelf for the last week or so. I ran into a kid in the aisle the other day (BUYING A CLONE TROOPER; YOU HEAR THAT HASBRO?) and he was looking at it, saying, "Who is this supposed to be?" (referring to Anakin). When I told him, he laughed and said, "Really? That's stupid!"

As for how the line will do, I think the first set will do well once it gets out there, but the OT set is going to bomb, the Hoth set will bomb, the Separatist set will bomb, and the 501st set will fly off the shelves.
Battle Sets (figure sub line - whatever the Dooku vs Anakin set is called)
These would be the Battle Arenas. While I didn't hate them like a lot of people, they were definitely overpriced by about five bucks, and depending on where you lived, definitely overshipped. After the first case or two (which is usually when people in my area have gotten theirs for the collections), the sets started to sit, particularly Mace vs. Palpatine for some reason (I thought it was the best of the three). As this was a "limited" assortment (as in it wasn't going to be ongoing, not as in it was produced in limited quantities), I don't think it's going to be a problem in the long run because they can do a clearance on the whole SKU and be done with it.
And you forgot one, Corran...Jedi Force. The line which was DOA unless you were more machine than man, and even he has become a pegwarmer in my parts. When Yoda and/or Vader are pegwarmers in ANY line, you know you've got a problem. Target doesn't even have them in the same aisle as the SW action figures, and the Luke/Speeder Bikes are taking up space in the Clearance aisle already, even at 6.99 apiece.
And I'd just like to say that the "Hasbro was caught off guard" crap is getting old in regards to certain lines. Since its release under the GH banner, the GH figures have sold consistently well and there is no way that the success of the line caught Hasbro off guard. Up until ROTS, I had never seen one of the two packs sit for more than a week, and they were constantly restocked. The Falcon and the X-Wing are sitting though, but the figure packs move and move quickly (even the initial ROTS sets are starting to move now).
