“We’re working on it,” says Schiller. “We have a team working hard on it right now, and we want to architect it so that we can keep it fresh with regular improvements, and we’re committed to making it our highest-end, high throughput desktop system, designed for our demanding pro customers.

We think it’s really important to create something great for our pro customers who want a Mac Pro modular system, and that’ll take longer than this year to do.”
