Pretty wild, huh? K'Kruhk (the Whiphid Jedi Knight) from their same wave often commands similar prices. I personally think Hasbro should do a special online- or retailer-exclusive two-pack with straight repacks of Jacen and Jaina just to help satisfy some of the demand and help drive down the prices of the single-carded versions from 2010 (Hasbro isn't seeing a single penny of that $89.99 so they have no vested interest in sky-high secondary market prices), but with the current transitional state of the Star Wars
3.75" lines and cost and corner cutting by the company I don't think such a re-release will occur.
At least not anytime soon.
