We’ll see what happens, I have a feeling Apple are focusing on weight reduction for a low heat comfortable experience with airpods level audiovisual transparency so the SoC could be with the external battery pack connected via a cable. So far these devices are popular with gamers, for art projects and other esoteric uses but I do not know if the upper limit in pricing would make this a compelling product and given Apple‘s fixation on control I do wonder if gaming companies will welcome this device especially since Apple has been at the throat of the company behind Unreal Engine and they might not be keen to cavort with their devil.I definitely think Apple should focus on increasing the power of their GPUs if they are going to never support 3rd party GPUs again, which seems to be the case. However, Apple isn't doing anything the way I would if it were up to me. Before even thinking about a VR headset they should be taking gaming seriously and making Macs with very powerful GPUs, and really push for game developer adoption, and buy some game studios like Sony and Microsoft always are. They should also make a game console version of the Apple TV also with a powerful GPU. But Apple isn't interested in any of this, nor are they interested in making a new Mac Pro with GPUs that beat out Nvidia and AMD.
Also if the VR headset rumors are true, we aren't even talking about a Mac Pro, because the headset is supposed to be a standalone device. It will have the graphics power of an iPad. Apple just doesn't care about the kind of hardware modern PC gamers care about.
As I said more and more of what we do is going to 3D, including the moving image field Macs thrive on. The AS M3 is meant to have ray tracing so at least it’s moving in a positive direction. The reason for high-end hardware is for development time; by the time the software is released on the hardware it’s meant to run on, things would have progressed significantly. We’ll see, Apple may do a Nintendo (low spec, more fun) if they do look at gaming or mostly focus on the human communication experience.
