Future MacBook Pros could themselves drive three 4K monitors at 60Hz, as Intel revealed that its upcoming Skylake processors have this capability. It’s even possible that Apple could create a MacBook Pro with Mac Pro performance, as Intel also announced professional class Xeon processors for laptops.

    What are you talking about? Real apples or Apple computers?
