Perhaps something is in fact happening with the Mac Pros. Just logged into the Apple Store for Education Institutions where I buy computers for my school & it shows a 1-2 week wait time on the top end Mac Pro. But oddly enough, when you click on it to configure it says "2-4 days." In the past when I've seen it jump from 1-2 weeks or longer, it's a sign that updates are coming. But all of the models need to say this (1-2 weeks).
