Sure if the model is a new higher end model. But do you see them releasing a 1” bigger screen model with small form factor still limiting how much power the machine could get for an extra 6-700$ price at a starting price at 2999? I don’t see how they would expect anybody to buy it with a small spec update maybe including Navi chips but I don’t see how they can offer anything higher than current 15” models to ask for a higher price besides a slightly bigger screen.
I still see apple dropping the 15” model in favor of the 16”. They can fit a 1” bigger screen into the current form factor on the 15” right now if they wanted.
Only way I can see apple having a completely separate model from the 15.4” is to bring back the 17” model.
There are a few changes that Apple could conceivably bundle into a higher-end 16" MBP if they so choose. For example, display improvements (OLED, higher resolution screen, improved color rendering), 802.11ax (next-gen WiFi), 64GB RAM support, new thermal design for more performance, etc.
I agree that if they do this it would be logical to drop the 15" eventually, perhaps with a less expensive 14" model also replacing the current 13" MBP, which could be an option for those priced out of the 16". The MacBook Air (with or without some upgrades) could then become the default 13" model for current fans of the 13" MBP who are priced out of the higher-priced 14" line.
No, the 15" retina was announced at the same time (WWDC 2012) as the refresh - the previous refresh was in October 2011. The closest comparison is probably when they released the 17" unibody in early 2009 not long after the 15" one in 2008.
Either way this mythical 16" model is more likely to be 2020 than 2019.
Hmmm, my memory told me otherwise, but a quick search seems to back you up, so you're probably right and my memory is faulty. I do agree that I think 2020 is more likely than 2019. I just think it's possible to see a new MBP in 2019.
Apple registering for seven new upcoming models (whether iPads or portable Macs) certainly adds some fodder for speculation.
