Much like i've mentioned with Teebo, I think Hasbro should do this...
Make one definitive "generic" wookie sculpt. Neutral pose, good (or preferably GREAT articulation, like VOTC Chewie), and then release him like that in a deco.... Any generic basic deco.
Later release an army builder of 4 figures, the same exact sculpt, all unique fur colors/patterns. Like a black with grey-ish stripes, tan, brown, and maybe older looking brown-grey.
Pack in a variety of weapons... Voila. Army Building Wookie goodness that, unless E3 blows chunks, would suck the $ right out of the collector's wallets.
Completists will want all 4 variants plus the carded. Army builders will want massive armies of all 5 figures, and extras to paint, and what kid isn't gonna want wookie troops?
Seems logical to me.
