Ah, another Chewbacca is already on the way (2 actually) in the snowy Chewie from the 4-pk and the Mynock Chewie.  I have no problem with him being made; he is a cool character, each one seems to get better than the last, and he sells.

As for Vader, I really can't wait for the removable helmet version coming up.  That one just looks sweet.  The one in the 4-pk though is a waste to me, I think they should have included another army-builder instead.

Bring on the Wookies and Sith Lords!
