I agree there isn't much here; but I'll pick up 1 each of the OT characters for my carded collection. Of these:
Luke: Surprised this looks to have so many new parts. The head sculpt looks new. It's hard to tell from the picture, but from what I see, it's not an improvement over the Resurgence of the Jedi head sculpt--possibly the contrary. The lower part of the shirt looks to be soft goods--which will help him sit. It's possible I buy one for my loose collection.
Han: I think the 2004 head sculpt looks much better on this figure than this one. Others have noted the shirt is not properly buttoned up for the medal ceremony. It's releases like this where it seems apparent Hasbro is going after collectors' dollars. For a kid who really wants a Solo, which sculpt is used really wouldn't matter; but a collector isn't going to simply buy a re-release of the VOTC figure. This figure is just different enough to suck some of us in. Like I noted above, this "different enough" will warrant a purchase for my carded collection; but it won't be in my loose collection.
R5-D4: Rumor has it, this figure is built with Build-A-Droid parts. The 2006 version looks a bit better IMO to the BADs. I don't need a newer, inferior loose version.
Stormtrooper: Not sure what I think about this one yet. "New gun" may not be enough to purchase a loose one. Though I say this assuming this is the recent Sandtrooper sculpt.
