I special ordered my TW book from the FLGS I go to and when I picked it up I noticed that they had a bunch more BT stuff on the shelves. Commenting on this - I'd assumed that they'd simply ordered more than the book just to keep some stock - the store owner said that "There'd been a resurgence" of Battletech, that they were starting to get more stock in for it and had made a deal directly with IWM to get in mini's! They were putting more shelf space devoted to Battletech.
Whatever you're doing, it's seems to be working!
