> in an updated Mac Pro chassis with best-binned M1X Max parts Yeah this seems realistic to me. Specifically, I meant that there will be no D1 (desktop-class chip) to complement the A14/A15 (mobile-class chips) and M1/Pro/Max (laptop-class chips). I agree that taking M1 Max, or future laptop-class chips (e.g. M2 Max) and adding better cooling and perhaps a chiplet would be most likely. That said, Apple's R&D is always for some grand future product vertical, not to make some more money over the next few quarters. e.g. Neural Engine and Security Enclave R&D leads 1. to on-device Siri + Face Id to accommodate a marketing change to focus on Privacy; 2. moves towards a password-less future. Even R&D for chiplets, may not make sense for them other than for Apple Cars. "Can you explain your unit economic analysis?" during a chip shortage, why sell 1 Mac Pro with a 10+ year "lifespan" when Apple could sell 5 iDevices with a 5+ year "lifespan" instead? e.g. had Apple known better that they would need to reduce iPhone production targets because of chips, its likely they would have delayed the M1 Pro/Max production/launch.
