Re: ARM on Azure and...
No reason why it couldn't be. For example A64FX from Fujitsu (that they're replacing SPARC64 with in HPC) is a good example that performance is not an issue. GPU is where the heavy lifting to great extent happens in a console, so the CPU architecture is less important as long as you got enough PCIe lanes.
Would make it bit more cumbersome for the PC-ports of the games tho compared to fairly effortless port.
