That will never happen. :-(((
Sadly Apple no longer gives a fuck about us professionals -- you know, people who use their computers day in, day out, for creating content. They would rather everyone use iPads for consuming content.
Before Jobs passed away Tim Cook was responsible for getting Apple's supply chain down from months to days. Apple doesn't want to be holding onto millions of dollars of inventory just sitting there taking up space. This means they remove options and "dumb down" the machines so there is only 1 (or very few) parts. Tim Cook has continued this obsession that it actually has become counter-productive. You can't upgrade a MBP to more then 16 GB of RAM because the RAM is soldered onto the motherboard? WTF.
Apple also has a hard-on for wireless. My current MBP (Mid 2014) has a whopping 7 ports (2x USB, 2x Thunderbolt, 3.5 digital+analog audio, 1x HDMI, SDXC card) and I LOVE it because I use all of them. Apple TV gen 4 removed the audio port because they want everyone to use WiFi streaming. It doesn't take courage to remove an audio jack on the iPhone, they are a bunch of cowards. Gee, oh look, 2 out of 3 "solutions" are wireless.
It is a far cry from the days of Jobs when he actually cared about building not only a cosmetic computer and a functional one.
i.e. When is the Mac Pro going to updated?? It has been over 1075 days!
The only thing Apple cares about these days is making money whilst they whore our their brand. Apple would rather sell over-priced "Beats" garbage headphones to ignorant customers rather then make quality products for the power user. Those days are LONG dead.
It is hard to argue against "Oooh, Shiny!" when all they care about is profits.
Apple is Dead.
Long Live Apple.
