These are actually pegwarming? That surprises me, especially for a wave that came out such a short time ago (wasn't it only about 2 weeks ago when they were first spotted?) and that one of its casepack brethren is a former pegwarmer, nay pegsmotherer, itself (the Droideka).
The WM I was at earlier today had restocked with one case of that wave and the Wookiee was the only one they had more than one of (two tans), but I think that had more to do with Hasbro's ass-backwards case pack ratios (see another thread for my "sky is falling" rant on that) than anything else, since I was the first person to see the figures there since they restocked.
The local Target has apparently restocked that wave about 3 times now, and every time I go in there, I see the Wookiees (again, the tan version) as the "signal" that I had just missed the Clone. However, every time I've seen the Wookiee there and left it, when I'm back the next day, it's already gone.
Tarfful's and Chewbacca's precedent setting as "WOOKIEE = PEGWARMER" might be spelling doom for the Wookiee Warriors (I still find the SP Wookiee, my favorite of the bunch, mixed in amongst figures at WM), but I honestly think/suspect that, if kids actually do get into this line once the movie is out, the Wookiees will start to disappear a little quicker.
Of all the characters on the pegs (that are at least familiar as far as species/race is concerned), I think the Wookiees will most benefit from their appearance in ROTS finally being shown to the public. If that clip on TRL last Friday (God help me I watched TRL and my head still hurts) was any indication, the Kashyyyk battle is going to be very cool.
Oh, and strangely enough, my brown Wookiee doesn't have any problem with his arm falling off, but the tan Wookiee, as Gatillo said, is apparently seeing Dr. Nick Riviera for his surgical reattachments.
