I agree with david1! The market is SATURATED with modern diesels, and Sunset/3rd Rail has many more potential sales for diesel models that have not yet been produced in 3RS. Models such as: FP7, FL9, FT (done CORRECTLY), and various passenger E unit models using the Sunset/3rd Rail/Golden Gate Depot new design power chassis, which came out with their new E7 models.
Personally, I will discourage Scott Mann from doing ANY modern diesels, until he "finishes" the older "historic" models, that have not yet been done correctly!
