I don't think you will see WBB competing with Lionel/MTH/3rd Rail on those types of engines(scale, highly detailed, and mostly accurate). Their dealer pricing setup will not allow that. As shown by the failure of the $800 Mikado, which tends to scare off many (high list / room for dealer discounts). From the WBB point of view Pacifics, H10s, and Mikado's have already been produced.
Without a command control system I don't see WBB jumping into the detailed scale engines. I always like to see competition but there may not be room for another.
Rusty, I know they have done them in almost every other scale except O.
