I've seen this wave a total of one time, at an Oklahoma City Wal-Mart about a month ago. Bought my two Clone Troopers, left the Kits and Saesees, and haven't seen 'em again since.
Funny, the Wal-Mart near me (not the same store) just stocked a ton of the (I guess) Wave 2 figures--Mace, Obi-Wan, Durge, and Asajj.
For some reason, I have a feeling that this new Clone Trooper isn't just a one-and-done figure. I think we'll be seeing a lot of them, in all kinds of different configurations, over the next two or three years.
