I doubt it. People have the best intentions. Then they buy a few things "on sale" from forum sponsors, then splurge a bit at York and Allentown, then bang!!! Lionel delivers 75% of the Signature Catalog Vol 1 in Nov/Dec.
Happens every year.
As for 21" cars, I think the shipping schedule still lists the American Freedom Train display cars as 21". But I recall reading those will be produced as 18" in length, since they're based on baggage cars. That's one of the reasons I'm getting them -- aside from the fact I like them too. Otherwise 21" cars are just gonna be too large for my new layout. I may keep my El Capitan, California Zephyr, Amtrak Zephyr, and Texas Special cars for display and an occasional run on the outer loop. But that's it for me in the 21" department. I've sold a couple of 21" sets already, and will have another one (3rd Rail's ESE) listed as part of the updates to my Layout Demolition Sale for Allentown.
