Rollbar looks like he is getting the Riccochet treatment at TRU as well. http://www.toysrus.com/product/index.jsp?productId=2388494&cp=&f=Taxonomy%2FTRUS%2F2254197&origkw=rollbar&kw=rollbar&parentPage=search
I'd bet on Tracks, myself. My local Target store still has three of him on the shelf (and one Meister), so he's going nowhere fast at $20 each.
Hopefully Silverstreak will pop up on there, lol I caved on the Riccochet the other day, I had the Smokescreen a long time ago from a 2 pack but sold it and kept Sideswipe. But after getting the 3 inch Smokescreen and Alt Riccochet I am liking the mold alot now wish I did not sell my old Smokescreen alt now.
