I'm with Quagmire. There will be a differentiation between low-end and high-end MBP systems.
But, there shouldn't be. Should just be MacBook and MacBook Pro, each in two screen sizes (13" and 15" / 14" and 16"). MacBooks don't have fans, MacBook Pro's do, and include more cores or some other "power" feature.
MacBook:
13" with Apple M-1 8-core / 8 or 16 RAM / Up to 2TB - $1299+
15" with same - $1499+
MacBook Pro:
14" with Apple M-1 10-core (or something) / 16, 32, or 64 RAM / Up to 8TB - $1799+
16" with same - $1999+
Something like that.
