While I have no doubt these cars will look fantastic, I'm quite surprised at the number of folks here expressing more than a casual interest in them -- particularly since so few layouts will handle them well.
Perhaps Lionel will have prototype samples on display at York? That would be nice. I remember that's where I first saw the AtlasO 89' flats, and I thought THOSE looked huge for most layouts... and that was just a low-profile flatcar. These autorack cars are gonna be far from "low-profile"... quite the opposite in fact! You won't be able to miss them if they're on display. 
I'm just guessing here... but I'm currently thinking these cars are definitely into O99 or O108+ territory before a layout does them any justice. And quite possibly even broader curves than that, before you're not dealing with excessive overhang issues. The ratings in the product specs don't necessarily correlate to what "looks good" -- rather they're simply a guide to what is mechanically possible.
