Well most of us have the comic con bust ups (clear) so yeah, they are kind of wee, about 2.5" tall for Han, the tallest of the clear bust ups to give you an idea of size scale.
I think most have preordered some form from EE as I am about to do, so they can get the clear Yoda. I only ordered the six pack, so working on luck/trade. I can certainly send you a Han if I end up with six, though I may need to trade one if I get only two. I expect you should have no problem getting Han/Chewie as long as you have patience, and then probably get them cheap.
I still cannot find mention of the chase versions other than on the various boards, and then only for Leia. I'm expecting one for the other series as well, but no mention anywhere.
I remain undecided on the Sith set, I may go for the big box, but no rush to order. That would preclude ordering too many stormtrooper sets from SSW.com. The extras with the big box are Vader/Maul, always popular stuff. I think being in Canada I can unload those fairly easily locally at a reasonable price, about $6 CAD.
The bounty hunters I'm concerned about - will there be a chase IG-88? I don't see how there can't be. GG is a pretty astute company and there would be no point to throwing IG-88 in a separate shipment, so my mind is set for a chase IG-88, driving bounty hunter fans stupid on ebay
Oh wait, I said all that already
As far as thoughts go, I only have the clear to judge:
The size is nice, fits well, not a huge space consumer. Detail seems to be great, but a little difficult with the clear versions. I like the appearance of the painted versions better and hopefull the paint application detail is good, as I would expect from GG.
They do concern me in one sense because you have to put them together. Some pieces like Han or Luke are fine, no real small parts and they fit together well. 3PO was a bit of a pain to put together and mine doesn't seem to fit well resulting in a bit of a disappointing appearance. My hope is the painted versions look less clunky. Leia is also concerning in so much as she has small parts (gun) and seems to fall apart fairly easily
Dropping her, especially the clear version is a major concern for me. Lost or broken parts are disheartening, to say the least.
Would like the GITD version also, for completeist sake, but waiting and watching on ebay. How much do I want to pay for them is the ever burning question.
