That's kinda what I see happening too, sometime in the coming weeks they'll be getting those ROTS ones in when Wal-Mart and TRU are putting out the ROTJ stuff... never know though. Also for TRU, the jacked up $10 price actually doesn't seem to be hurting them in my area, which is weird. They've had the best selection of vintage figures so far, so I guess that's why they are moving out here at TRU.
As for Vader, I've been surprised - he's really not pegwarming at all anywhere now at the stores I hit on a regular basis. Not even at Target, who has a ton of Wave One still.
