I never said that M2 cannot be a better version of the M1. All I'm saying is that an M2, with 20-30% better performance compared to M1 would not be enough to satisfy the pro market.Why don't you think a M2 can't also have a 4+4 CPU cores and 7/8 GPU cores variant, but with more performant cores?
Similarly the M1 cores can be scaled up as well.
Apple needs a different class processor to address the pro market.
