I don't think that will happen anytime soon. I think they haven't found anyone to make the aluminum razors in the States.I'm sure ATT will come out with an aluminum X1
I saw this on their Website as a response to a customer review. And it was back in January:
"Our Aluminum production has been on hold while we look for a new machine shop to manufacture our Aluminum line. I believe we have found one, at last. However, our entire Classic line was retired last year, so any new aluminum that we have made will be of the Windsor design."
