The worst would be some proprietary port - not TB3. A little better would be if they use TB3 but fit eGPU in ATD and you will not be able to upgrade/replace it. IMHO this is the most probable solution to expect from Apple. Then they can fit it in ATD and make it upgradeable. IMHO contradicts Apple paradigm but who knows - ATD is a long living device, you don't change it every two years. They might also give external GPU unit but this way GPU manufacturers will have the profit instead of Apple. Does not look like Apple-way to me.Assuming Apple would budge to the pressure of offering an external GPU solution via TB3. Would it be like the "Core" extension of Razer's Blade Stealth or would Apple go a proprietary way and e.g. be coupling that with a (long overdue) updated Cinema display (thinking of their patent of a monitor functioning as some kind of docking unit)?
So my beliefs are in 3rd party eGPU solutions using support for the official one.
If they still use TB3 and standard GPU but just place it in Apple Thunderbolt Display, 3rd party solutions are likely to benefit from this support.And if they'd do the latter, would 3rd-party-solutions with a simple box including a PCIe slot still be supported / working on a Mac?
