Over half the sales to this point have been in ERR upgraded locomotives. If I were to count on only existing TMCC stuff, there's only a finite number of those around, when they're gone, they're gone. Also, the lack of the Cruise Commander M means that some people won't want to upgrade the existing TMCC locomotive if they can't get cruise, I know I wouldn't.
I'm keeping my options open, but as of now, I don't see my way clear to tie up thousands of dollars in inventory that I may never sell, or would end up selling for fifty cents on the dollar. As others here, I am still holding out hope for a change in Lionel's posture, but quite frankly it's a pretty slim hope IMO. The message we all received seemed pretty finite that the ERR end user sales would cease. Since not even a hint of an alternative was mentioned, that didn't bode well for the future.
Let's just assume this posture and hope for the best.
