Judging from what many have said online here, and by the scene here locally, I'd say the OTC (and VOTC for that matter) was a success. When the OTC line first hit, it seemed to sell pretty smoothly, even sold out on a number of occasions. It was usually pretty quick to be restocked, but continued to sell well. Recently, like many of you have mentioned, we had a butt-load of Endor Generals alongside Bespin Leia and Lobot hitting the pegs (at Wal-Mart in particular), and I honestly didn't think those would ever sell. They sat there for some time. Then right around the week before Christmas until now, it has pretty much cleared out. The Star Wars section at Wal-Mart is currently empty, with the remaining OTC and VOTC being moved to the clearance aisle, but there isn't much there either. I'd guess around 10 or so General Landos and Bespin Leias, and a few Madines...although those seem to be slowly disappearing, probably for customs. Target is clearancing out what they have left as well, which at our closest store seem to be pretty much just Bib Fortunas and Lobots. Again, not a ton, but those are pretty much the only figures there.
The VOTC is a line I really liked. It was the same here as many others have said, WAY too much ANH wave in the beginning. I really didn't think many of those would ever sell. Despite his pegwarming legend, I couldn't go and buy a VOTC Han Solo in our town now though, and there are hardly any VOTC anywhere. TRU hasn't had any for a month or two now (and only Saga figures now by the way), between the two Targets we have in town there are 2 Landos, and Wal-Mart had about 5 Landos and 2 Leias, all on clearance. I was surprised that these were all that were left, but its good to see that they sold well, at least in some areas, so hopefully Hasbro will revisit the general concept in the future.
Overall, I think the OTC and VOTC lines both did pretty good. Taking the repacking concept of the OTC into consideration, it did almost "scary" good. Sure, they looked good, and the cards were fantastic...and really the figure selection wasn't all that bad, but I hope this doesn't become a continued trend either. A few here and there (well chosen), is ok, but not a line with 75-80% repacks. But, overall, it has sold very well here and there really doesn't seem to be all that much left....and what is left, is already on clearance. I'm glad to see its getting cleared out, and hopefully we can see some new (IE Cantina, Animated Clone Wars, and Preview Waves) hitting the pegs in the coming weeks/months. Long answer short...I'd say yes, the OTC did pretty well, especially considering the circumstances.
