I ran across a blue CC at Walmart this weekend and picked it up. The date stamp on this figure is 20611 while the black CC that I bought from Target, on launch day, is 20751. That would date the blue version earlier than the black.
I have 4 GI Joe troopers, 2 each blue and tan helmets/cloaks. One blue version was purchased at Walmart at launch and the two tan versions were purchased at Target, one on launch and the other a week or so later when they put up another case. The second blue version was picked up for me by a friend and I forget now if it was at Walmart or Kmart.
One blue version is dated 20621 and the other is 20651. Both tan versions are 20751. I mixed up the two blue versions so I don't know now which I bought and which came from another location.
On Sunday I spotted two blue version GI Joe Troopers and, I believe, a blue CC at Toys-R-Us. I didn't check the date stamps and for the price they charge, didn't buy any. I don't know how long they've been there, the pegs were pretty full, so they could have put out multiple cases at launch and not sold any, sold through and restocked or just filled up partially empty pegs.
If I had to make a guess, I would guess that the black CC and tan GI Joe Trooper are the running change and that they were meant to go forward. But, with the line being cancelled and coming back next year, anything could happen. There could still be cases of each out there waiting to get stocked, Hasbro could be holding on to more W1 and we don't have any idea yet what's already packed up, as carry forward figures, in post W1 cases. We also don't know yet if Hasbro will go back into production on W1 characters either as additional W1 case packs or as carry forward figures and what version those might be.
Lots of stuff up in the air right now. But, again, if I had to guess, if there had been no interruption to the releases, we probably wouldn't see more blue versions of either figure after that first release.
