I can report that the B&N at the Grove (in Los Angeles) isn't clearance-ing them out and was told that they just had a reset (?) which committed them to supporting the line (at least for awhile longer). But they then went on to say that they are at the world-famous Grove after all and if it were a matter of some stores dropping the line, this store wouldn't be involved.
But they did have an Imp Aces with an Intercepter sporting a detached wing that I was able to get for 50% off after asking for a price adjustment. I figured a bit of gluing shouldn't be too difficult.
