Not necessarily. A 15-inch model can be thinner and lighter than the Pro models.
I suppose the 13-inch M1 was just a carryover and Apple kept it just to justify the price points. Now, keeping the 13-inch M2 Pro model makes little sense as it is $100 more expensive than the redesigned Air and I can see any advantage in buying it instead.
The new 13-inch M2 model can only mean that a new MacBook model is around the corner and it was not ready for launch this time. This is because:
- If Apple intended to simply discontinue the 13-inch Pro model and replace it with the new M2 13.6-inch Air, it would have already done so. In this case, the 13-inch Air and Pro would have both been replaced by the new Air. This did not happen.
- If Apple intended to replace the 13-inch Pro with a lower-end 14.2-inch Pro, with the same chassis of the M1 Pro/Max 14.2-inch model, but with an M2 processor instead, it would probably have done so as well.
- If Apple intended to replace the 13-inch Pro with a new 13.6-inch Pro, with a chassis shared with the new Air, but with an M1 Pro/Max processor instead, it would probably have already done so.
Then, my conclusion here is that the 13-inch Pro will be replaced by something else. It may be a 13.6-inch Pro with a slightly thicker chassis, but it might not make sense as it would be too close in size and weight to the 14.2-inch model.
The more feasible option, it seems to me, is a forthcoming larger Air model. A 15-inch model that could weigh some 3.3 lbs and cost from $1399 to $1699.
So Apple's line-up could be as follows:
Previous gen low-end Air, $999
Low-end 13.6-inch Air, $1199
Low-end 15.2-inch Air, $1399/$1499
High-end 13.6-inch Air, $1499
High-end 15.2-inch Air, $1699/$1799
Low-end 14.2-inch Pro, $1999
High-end 14.2-inch Pro, $2499
Low-end 16.2-inch Pro, $2499
Mid-range 16.2-inch Pro, $2699
High-end 16-inch Pro, $3499
Makes sense?
