This is excellent news. Even if you don't end up using one, I think it's motivating if a powerful upgradable Mac Pro exists. Something to aspire to. Depending on your area you might at some point have to do lengthy computations or you start working with deep neural nets and then want to have Nvidia hardware. I think it's great if you can stay on your favorite platform and have everything on one system. Also: continuous integration for iOS. If these machines will be reasonably priced it will result in faster test build times for many engineers out there. So I'm very happy about this unexpected announcement.
