Our local TRU is the same way, haven't seen new LOTR (or ML) stock since we moved here 6 months ago. They have an endcap filled with Gollums, and a few of the other boxsets (TABA, Ringbearers clear pack), but that is it. Also, the Gollums are the old boxed style. Target and Wal-Mart are restocking with older waves of the Trilogy line as well, haven't seen anything past the Morgul Lord/KOTD wave here this year. At least the newer figures seem to be offered online fairly regularly and somewhat cheaply now, I see even Amazon has (or has had) some of the newer waves from time to time.
I've been wondering too how much longer this line would last. Although I don't know nearly as much about it as many of you do, and have a pretty small collection, I'll be sad to see it go. But, at the same time, I don't know that there is much left to make aside from getting into numerous resculpts of the main characters...which probably aren't needed. Plus, at least around here, it sure looks like it is losing retail support without any new movies on the way.
