Just caught on the toys r us website that the TRU exclusive disc packs are back in stock online. Not sure if they are restocking Mike's car or if they are getting the new tron ones but i ordered a couple. (didn't get any of the first shipment so i'll take either. won't get delivered till probably next week so it'll be a while till i know which one.
I gotta say TRU should really change the description of the item online. "You won't know which 2 discs you get until you open the package".
