That's certainly encouraging news. If this happens then I may just add a third SD40-2 if it meant a certain road name being done. So far I have 3 in mind.
Even if 2021 is a no-go for the SD40-2 what harm is there in keeping the model on the website? Either you want the model or you don't and I want it so if that means waiting another year or two then I'm OK with that.
