Its not what makes me sleep better at night, its the reality. PPC wasn't abandoned by Apple because x86 somehow stopped being inferior, it was abandoned because it was more mainstream and available. x86 is OLD. Moreover, x86 isn't going to make or break third party support. Nintendo doesn't have third party support because many (if not a majority) of its gamers do not buy third party. People buy Nintendo for Nintendo first party titles and the occassional third/second party exclusives.

They are either going to do PPC or they are going to do ARM. If they go x86 I will eat a hat. Only Sony and MS were stupid enough (Sony less stupid and in much worse financial straights, and they needed cheap units and couldn't afford to sell at a loss) to go x86 and try and compete with PCs.

Nope.

Apple abandoned PowerPC because Intel had a better roadmap and IBM was not willing to invest in the PowerPC-Architecture. Apple wouldn't be able to build a MacBook Air, that lasts 12 hours with a PowerPC-Chip. Intel has much besser Perfomance-Per-Watt.

What do you mean "Nope". That's exactly what I said. They trashed PPC because they didn't want to invest in the R&D themselves when x86 was offering better alternatives at cheaper prices. x86 has always had more legacy bloat to it. PPC and ARM have much less, but PPC was all but abandoned because no one built a roadmap for it and no one wanted to invest in the R&D.

Apple was pushing for it to go mainstream for years but it never picked up. ARM, fortunately, did with mobile and now is a solidly developed and R&Ded architecture.

That had nothing to do with "mainstream", they made the switch already in 2005. They just were not able to put a G5 into their laptop, because it was too hot.
