Haven't really interjected here yet...
In my neck of the woods, this is what I see:
-TONS of droids... SBD's, BD's... They are pegwarmers extrordinaire out here. If the SBD were just the AOTC basic one with a more poseable right arm, i'd have bought it. I actually liked that figure but just wanted a poseable right arm. Greivous' guards also sit, however I too noticed they sold well at one point.
-Collection 1... Guys like Tarful, Chewie, the main Jedi (Yoda, Obi, Ani, Mace), are all warming pegs in every store. They're subsequently the worst quality figures int he line it seems as well, so no surprise there.
-Collection 2... Really only the Jedi sit here. Even Prego Amidala isn't TOO overly common. Of the Jedi, I see more Plo and Sae Sae than anyone, and really Aylya and Agen Kolar have all but dried up. Luminara and Shaak Ti are sort of on the in-between level, or as abundant as Plo/Sae are.
-Bail Organa is a pegwarmer, and that sucks. He's a good figure. Along with the C2 Jedi who are sitting some, Bail lingers. He's boring, it would happen. Even I haven't bought one yet, and he really is a quality looking figure.
-Figures are MOVING slowly. Even "pegwarmers" I've noticed are moving somewhat slow but steadily. My Targets have an endcap at the registers of figures, and just watching them dwindle down to fewer figures EVERY time I'm in the stores here, that tells me that the kiddies are getting their attentions wrapped around SW again. That endcap at my nearest Target is almost dry of figures now. Sneaky of them to put that at the registers like candy. A nice impulse purchase thing for the parents to shut their kids up. Oh that's shrewd!
-Clones are GONE... I'm lucky to see a #6 at this point, much less a Commander, Pilot, or whatever... Clones are the HOT figure, there's not a doubt about it. The Guards are also long gone, both blue and red. These are hot items. Even TRU is out of the #6 Clone and they used to have him in semi abundance at one point.
-AT-RT's are only now starting to sit, as is the ARC-170. Used to be that these two vehicles were impossible to find. The Boga, Greivous' bike, BARC, and Jedi Fighters have sat from day one though... THe surprise ship of the line then? The Tri-Fighter which I have seen only once, didn't buy, and now wish I had one. See, quality does outsell its lesser competition!

The AT-RT still moves, which is good, but it's starting a little back up now. That's expected with vehicles I suppose.
-I've yet to see a Mustafar playset. They're out I was told, just recently showing up at a local WM for the first reported time in my area, so it's tough to judge there.
-Attacktix is surprisingly picked through at Local Targets. I notice how it's always a jumbled mess, even after I know it's been fixed. I think it's selling slowly perhaps.
-Board Games = Clearance.
-Playskool Figs don't seem to be moving... Those big figures. I see the same stuff every time.
-GalacticHeroes have hit the wall and are sitting right now, but that may just be the selection. That line has weird popularity.
-No Darth Taters in sight. I've yet to see this, and now I actually sorta want it.

That's Pittsburgh in a relative nutshell... I'm sure I forgot a figure here and there like 3po (not all that common in my area, actually), or Dooku (again, 2, maybe 3 on the pegs at any given store, but that's it). If I forgot to mention them, they're likely selling and not something I see rifling through the pegs.
Yoda is perhaps one of the all-time pegwarmers in ROTS. An irony that will perplex Hasbro and retail since he was the "hot" figure in AOTC's launch for some time. His figures suck though, and 2 at one time seems not such a great idea anymore. I'm not surprised at a lot of the Collection 1 stuff sitting then.
