Disclaimer: Second-hand info, and I don't know how much is factual. But it seems reasonable. I discussed this with Dick, owner of Hobby Depot. He said that he has customers regularly calling him for new NASCAR model kits, and has all along. He told me that the main reason for no newer kits is because of the Car of Tomorrow. Not so much because they were generic, but because NASCAR declared their design to be their intellectual property, and only allowed companies to make models who were willing to pay exorbitant licensing fees, like 200K-300K per model - and this left pretty much die cast companies as the only takers. This was also one of the things that upset the car manufacturers, until Ford and GM reportedly threatened to pull out of racing unless they were allowed to run cars that actually resembled what they sell. Thus, no more CoT as of 2013. The manufacturers now own the car designs. Will they loosen up on the model companies? It would be nice.
