That guy's great when it comes to sussing out future software---I don't know that he has any sources re: hardware.He just says yes to the question, also how long is soon? personally i'd like to see one at WWDC. Announcing the Mac Pro, Pro display and the new Macbook Pro with a new redesign, would be a great fit for WWDC, Pro machines for a Pro audience. However WWDC is mainly about software, altho they do sometimes announce hardware (see WWDC 2017).
My personal feeling is we're going to get new Pro focused hardware at WWDC to go along with Mac Pro preview/announcement; pro focus meaning new MacBook Pros.
