I reckon this announcement confirms what I’d previously said / believed - that the Mac Pro was going to be ended and replaced by iMac & iMac Pro range, but now will also live on as a super high end range above both, thankfully. If this is the spec they are putting in the iMac Pro, then the real Mac Pro will be (rightfully) an absolute monster I’d guess!
As an aside, as someone who had a client with 3x 27-inch iMacs all have their AMD video cards die from overheating in the same week (last week!) there is no way in hell I’d buy an iMac with an 18-core Xeon and a hot video card. New thermal design or not. (where have I heard that before… oh right, with the Mac Pro )
