I saw this personally at a local Target and Wal-Mart yesterday. Wal-Mart's wasn't as noticeable, since there were still one or two each of ROTS Obi-Wan, ROTS Anakin, R5-D4, DSE Luke, Ceremonial Han, and a single Endor Trooper. Target, however, had ZERO vintage figures on the pegs, since their entire stock consisted of ROTS Clones, Cloud Car Pilots, Sandtroopers, and Dengars. TRU wasn't touched, as pretty much everything pre-FOS display disappeared during their last 2 for 11 dollar sale.
So far, from what I've seen, the figures that have been pulled are:
-Cloud Car Pilot
-Clone Trooper (ROTS)
I'm just curious how long it will be before stores get huge shipments of Wave 5 that will clog up the system again.
