Yeah, there is definitely something fishy going on with the Macs right now. I've written many times before that I think they might be working on gearing them up with ARM chips—especially given that Intel announced in August that they are going to begin manufacturing ARM chips. We have A, M, S, and now W chips. Perhaps they'll go with something cool, and everyone knows there is no letter cooler than X, which is like super eXtreme. I mean, the fast iPads get A_X chips, and X has had an important place in the previous Mac OS X branding for the past 15 years. Maybe they could call it the X1 Fusion chip or something.
The only problem is there are lots of Macs, with different speeds and price points, so how do you name them all? Maybe they could just list specs like they do with current Macs: "3.2GHz octo-core Apple X1 processor" for things like iMacs or "2.4GHz quad-core Apple X1 Fusion processor" for things like MacBooks. Or they could break them out into different lines, either with different letters or with different designations at the end. So maybe the MacBooks and MacBook Pro 13" get the lower tier X1 base model, MacBook Pro 15" and iMacs get the middle tier X1S, and Mac Pros get the upper tier X1X. Each tier would have a range of speed within that class meant to hit different energy and thermal dissipation requirements. Each tier could also be delineated by a different number of cores, or configured with a Fusion package to meet low power requirements.
I'm going to be pretty disappointed if they've gone silent and just release a pathetic spec bump update. My personal dream machine would be a 16" 4K rMBP with reduced bezels around the display so it's the same footprint as the 15", OLED Touch Bar across the top, Touch ID, 12 hour battery life, hex-core or higher Apple chip, latest Nvidia graphics (is it even possible to mix that with ARM?) LTE and GPS (for locating), better FaceTime camera, 4 x USB-C/TB, and mLED (micro LED) true-tone display. It doesn't really need to be thinner and lighter, because it's a freaking laptop, but I wouldn't mind losing just a little weight if they can hit the specs above. No chance in hell of getting all of that, but half of that would be a good start. Macs have just stagnated and there's absolutely no reason to upgrade my mid-2012 rMBP 15" when you look at the current lineup. I know part of that is Intel's fault, but all the more reason why Apple should design their own chips for Macs. They even renamed it to macOS recently. It matches everything else on ARM hardware, so why not run it on an advanced version of iOS hardware?
