I just placed my order with J. D.'s Trains. J. D.'s Trains (www.jdstrains.com/ ). I just talked to Jeff and he confirmed that he is definitely going to do the Wabash E7 and the Texas Special E7 (call him if you want the Frisco version, he hasn't decided). They will be produced by 3rd Rail, whose version has received a lot of compliments on some of the boards on this forum.
The Wabash E7's will be a real treat. I don't know if they will ever be done as well again.
