If they want to be exact, they probably should wait. The Exact Rail car is a model of a TRG built boxcar. All of the cars with the new logo I have seen were built by Gunderson.

Here's a pic of an FBOX car in TTX's new logo. Maybe Exactrail should come out with a 50' high cube with the new logo too? They already had a couple of runs of 50' cars with the now-old TTX logo.
