Found another (older) article that talks a bit about potential entrants for next year:

At around R1.3-million, a new GTC car will also be much more affordable than a current Production Car racer. The purpose-built GTC cars will feature a single specification tubular chassis wrapped in metal bodies supplied by various manufacturers which as of now include Audi, Ford, Jaguar and Nissan. Engines will be limited to 2-litre turbo units, with computer management systems strictly controlled in order to keep racing and budgets as close as possible.

Production Cars’ two Audi teams – Sasolracing and Engen Xtreme – have confirmed they will switch to GTC next year with existing driver line-ups of Hennie Groenewald and Gennaro Bonafede, and Michael Stephen and Simon Moss respectively set to remain. The Audi teams will likely use A3 Sedan bodies instead of current S4s. Gary Formato will compete in a Ford Focus-bodied car, and there has also been interest from privateer teams looking to enter BMW 2-Series Coupés.

The current crop of Production Cars will be allowed to compete in GTC races, but in a lower tier GTC Lights category. GTC Africa aims to start the 2016 season with a 12-car field.
