The 16" Mbp will clearly have a much improved chip than the A14/14X and apple i bet is working on a custom made gpu to replace the need for the dGpu from the bigger imac and the bigger macbook proIMO, it's a revived 12" MacBook.
- It's the least demanding of all Macs, so it's safer to start with this one,
- It's been out of the line-up for so long, but there's still a market for ultrabooks, bringing it back only makes sense
- Macbook Air was refreshed not so long ago,
- The MacBook Pro has to be a "pro" model. An A14X probably won't suffice for that matter.
Just my opinion.
