I completely get that the OP is trying to convince himself that it is still possible a 14" version will come out in the near future, but the reality is that Apple made it pretty clear what its intentions are for the time being when they released the 2016 MBP, unfortunately. I was also a big advocate Apple moving to a 12-14-16 screen size line-up for their laptop offerings. I think it would have been a smart move not only from a product standpoint but also marketing.
They could have had:
- 4.0", 4.7", 5.5" iPhone sizes
- 7.9", 9.7", 12.9" iPad sizes
- 12", 14", 16" MacBook sizes
- 0", 21.5", 27" iMac sizes
It would have followed the classic good-better-best options, and kept things super simple.
However, when the 2016 MBP came out with the same screen sizes, and an nTB "value" option, it was pretty much clear that the MacBook line was going to remain a single model. As has already been said here, the nTB MBP was even singled out as the 13" MBA replacement during the keynote introduction.
I feel like they made a mistake on that one, and am pretty sure that the screen sizes, which are pretty industry standard screen sizes, have been kept due to cost, which is a shame, considering they seem to be able to pretty much charge whatever they want to in their MacBook line these days.
The 11" and 13" MBA alongside the 13" and 15" MBP line-up made sense on the laptop side. You had a super portable 11" MBA, a 13" MBA where portability was priority over power, a 13" MBP where power was priority over portability, and the flagship 15" MBP with dGPU options.
You could have had the exact same differentiation using a 1" (not even really - 0.4" up to 12", 0.7" up to 14", and 0.6" up to 16") larger screen and had something to really put some nice marketing spin on. Especially with the Kaby Lake m-series of chips changing name to i5 and i7 on the higher end, it would have been well placed to introduce a 14" variant of the MacBook.
- 12" MB - base m3 with Yi5 and Yi7 options
- 14" MB - base Yi5 with Yi7 option
- 14" MBP - Base 15W i5 with 28W dual i5 and dual i7 options
- 16" MBP - Base 45W quad i5 with quad i7 and dGPU options
But that all went out the window, at least for the next few years, until the MBP gets a minor mid-design facelift. Now instead you've got 4 distinct options at 13" - legacy MBA, 2016 nTB MBP, 2016 TB MBP, and 2015 13" MBP. Let's not forget the 2015 MBP is still being sold brand new as well!
Same sort of thing is up in the air now with the iPad line. They've got a good to better option on the 7.9" model, a better to best option on the 9.7" model, and a best 12.9" model. With all the talk of a 10.5" principally bezelless redesign being rumoured, it will be interesting to see what actually comes out. Would love to see a redesign that takes strong cues from the iPhone 6-6s-7 design with rounded edges, and a matte black option, but if we concentrate on screen sizes, what happens then? I actually don't think they will have 4 screen sizes to choose from. I think the days of the original 9.7" screen will be numbered. It will probably be a 10.5" and 12.9" pro, both having the same resolution and the old 2048x1536 resolution will be kept by the 7.9" model, which on the high end will get an A10 processor, pencil support, true tone and a "Pro" moniker, while the iPad mini 4 will remain alongside the Air 2 as the low price options.
For iPhones, I would absolutely love to see the SE get some love for a 10th anniversary edition, adopting the iPhone 6-6s-7 design in a 4" form factor with an A10 processor, the iPhone 7 stays on as last year's model and we get something neat on iPhone's 10th anniversary for the new model. Probably pie in the sky (just like a 14" MB at this point) though.
