No it won’t. Apple is dropping the A#X-series in favor of the M-series chips since the M1 is basically what the A14X was supposed to be. It makes no sense for them to have two identical SoCs with different names. The A-series chips will be lower-power, lower heat, lower power consumption and slower than M-series counterparts.The next Air will most certainly have an M1... if not an M2 even. With the next generation iPad Pro getting the M2 after.
It's an obvious evolution now that Apple is reducing chip design lines.
Also, the question of why Pro then?
Easy... more ram, larger storage options, 120hz screen... this isn't complicated to figure out.
Basically: if it had an A#X chip, expect it to be upgraded with the M-series. If it had a non-suffixed A-chip, it's staying on the A-series.
Again, no. Most likely it will get a later A-series chip which will probably be on-par with or faster than the M1.Won't get the "full" M1 chip, likely crippled with less big cores like the current one.
