As a user I don't think I'd ever go to .new directly. If you've got some other way to get users there from the main site, you might as well use a query string, path, subdomain or some combination of the three. I'm not a web dev, but I've dabbled a bit over the years. So I guess I could be missing something. I'm sure the right marketing could make this work.
