I've seen a few sets at TRU and the new Tie Fighter at a Target this past week, but apparently Walmart is putting theirs out on 2/10, as seen in these cardboard placeholders the Walmart in Sterling/Dulles VA.

My local TRU had some of the sets, including the Y-Wing, but no X-Wing or TIE Fighter. Other than that, the only other places that have carried them have been smaller mom and pop toy stores in my area. But even then, none of them seem to have the X-Wing. My local Target and Walmart didn't have any of them.
