Will PS/XBX follow Nintendo's footsteps?

Nintendo choose ARM because it was the only possible choice for their hybrid form factor. But if you want more CPU performance in gaming, X86 is still the way to go.

Also, don't get too hyped over the performance for Apple's new Laptop chips.
First, they're one process in front of AMD and 2 in front of Intel with the 5nm process, so they had more headroom from that.
Second, comparisons with x86 CPUs get a bit unfair at this point: Apple emphasized the singlecore performance - but was actually comparing their singlecore vs Intel's singlethread performance. if you fill the core with 2 threads to make a correct core vs core comparison, then the old Intel chip still stayed in front.
Third, the new MacBook Air comes with a hefty 68W PSU, implying that the chip doesn't pull less power than their previous Intel chips (which had PSUs that were only rated to 62W)

The new Apple silicon is great, no doubt about that. But it's not the be all, end all that you seem to make out of it.

Microsoft is also only using the new ARM for their Surface tablets and laptops, which are supposed to have great battery life over pretty much everything else. But don't expect them to massacre the x86 chips, that simply won't happen.
