I think the whole idea of a 13” MacBook Pro with M2 makes NO SENSE. Buy the M1 model at discount, buy the M1 Air, or wait for the M2 Air. I’m confused as to why Apple is keeping the Mac line fragmented.
Well, as far as I can see it is only one rumour, and the main reason
that rumour stands out is that it
is a bit surprising c.f. all the other rumours that sound like plausible guesswork.
Personally, I agree that the low-end 13" MBP (non-touch, then 2-port) hasn't made sense to me since the intel days and I'd either get a tricked-out Air for the same price or stump up for the all-round better 14" - but Apple have the actual sales figures and I don't. If the 13" MBP and $1300 price point are appealing to a particular market that is making Apple useful money, it's going to get some sort of update.
Thing is, the M2 13" rumour doesn't say what
else is getting released. It doesn't contradict the rumours about the new Air or MBP, and the 5k iMac replacement has never been a strong prediction for March. One thing that makes
less sense than a M2 13" is
keeping the M1 13" alongside an M2 Air that will probably outperform it.
The M2 seems to be intended as a direct replacement for the M1 (and, as someone else has already pointed out, could quite conceivably be a pin-compatible,"drop-in" replacement) so once M2 production is cracked, Apple would probably want to end (regular) M1 production ASAP to free up capacity for M2.
It's not like Intel where there's a huge OEM market and the last couple of generations of chips would remain available to order for years - if Apple no longer needs M1s, nobody else will be buying them.
So anything with M1 that isn't being dropped or replaced will likely get bumped to M2 pretty pronto. If we
just see an M2 13" MBP, and not M2 Minis, 24" iMacs and Airs (maybe not at the next event, but soon) then it would be a bit weird.
