OK guys, M1 time is over. What's next?

Something I just realized, and I think the timing works out beautifully:
TSMC started N5P testing/Risk production in 2Q2020.
Meaning that (and now that I think about it, it is so obvious!) the M1X will be on N5P!
THAT is what's determining its schedule.

There is a precedent. Remember that the A10 came out in Sept 2016, on 16nm. But the A10X came out in June 2017 on 10nm.

This makes so much sense. It gives time Apple to improve some of the rushed bits of the M1, and gives a free 5% speed boost (which isn't much, sure, but may mean that M1X clocks at, say 3.5GHz)
And gives Apple a second round of (totally justified!) "OMG, Apple is king, everyone else is doomed" publicity, say maybe in April or May, which should sustain them till the A15/iPhone next reveals in September.

Well, six months or so to see if I'm right. tick tick tick
