Almost certainly. I’m glad they failed to buy it. It would have been a mess in the long run, but clearly they have plans for ARM.
Yes, but that chip is old. It was already a bit outdated when the switch came out, and that was 2017.
Correct, but they do work with ARM already. I’m guessing they will be making the chip for the Switch 2, which will probably be out of date when it comes out in 2024, but it will be a more modern chip.
