I think they've done better than people are thinking... When they released at Target, at least here, they sold through probably 8 times in the first two weeks. That's a lotta figures.
WM got a later start and deluged the pegs a bit more but I'd say they've sold through half what they put out.
I thinkt hey've slowed down but I think PM will take this line to a more collector-only level. I'm hopeful to get this wave... And more in the future I hope. I'd like to see WM do a good sale to clear out what they've got for future stuff, as I'd love to stock up. At $5 a pop I'd buy a full set and an extra set probably, just for the seats/consoles.
