New 2018 Hot Wheels 67 Camaro for RLC Members?

Two new Hot Wheels cars were recently spotted on auction sites. They include a light blue spectraflame 67 Camaro and a yellow spectraflame 68 Cougar. Both have the "50th" anniversary logo of Hot Wheels on the doors. Could this be a sneak peek at the upcoming releases for the 2018 Hot Wheels Red Line Club?
