AOTC wave's had sightings in Asia, so I think we'll see them either early January or by the end of December. Not far at all.
I agree though, ROTJ hasn't shipped well enough yet for my liking either. Luke, Endor Rebel, and Gammies are hard to find, and Wicket's a close second, and then Woof, Ackbar, and R2 are the only things anyone sees routinely at this stage. The $6 price is making stuff fly too. It's easy to say, "Eh, what the hell", on picking up a Sandtrooper or Clone...
At Target here, Sandtroopers have become almost impossible to pick up, actually, as has much of the ROTS Wave which had some pegwarmers for a while there like Anakin.
They're down to pretty much nothing interesting these days. WM's getting there too.
