One item not considered with this licensing is if it there is an exclusivity clause in the agreement that prohibits the use of TMCC. I don't have a speculation either way, but it is entirely possible. However from a manufacturer's standpoint it is logical to use a single command system in general to minimize complexity. I will continue to watch and see what happens. Personally the only command system that matters to me is DCC in 2 rail. I don't see much benefit between DCS or TMCC in 3 rail as long as the system is reliable as mentioned above.
