EB kits have been clearancing like mad... The due-date has come and gone though now in just the past couple weeks here, but I wouldn't put the "rare" lable on that figure at this point. I'm sure someone otu there has a number of that Chewbacca available. Honestly I'd like a couple more but the one I have will suit me... The sets were in massive abundance around the country though, and many clearanced low quickly, so I'm sure the figures from the set will become available via trades.
Put it on a want list, you may get a taker. You figure if someone got the set on clearance, they'd perhaps sell the figures for what average retail is on figures... That's not a bad deal for everyone involved.
