I heard it from a friend of mine who is very close to Yokomo Japan team, he told me that Yokomo is developing a new TC car but no release date has been planified yet.
I also had a chat with Yokomousa who confirmed the development of a new TC that should be released next May.
I don't know if it will be belt, shaft or a mix... just wanted to know if anyone else has more info.
