MagSafe won't come back, at least not in it's previous form. There are some great dongles out there now that replicate the functionality - I'd love Apple to add something like the Snapnator directly into the power connector/cable.
In terms of what I'd like to see:
- Non-Touch Bar 15" model
- The UI lag eliminated - it's really not acceptable on a machine thats meant to be top-end
- A <£2k entry price for the 15" model in the UK as the current models are over-priced, even by Apple's standards
I would not say overpriced. Looking very closely at the specs, not just CPU, GPU and so on, I was not able to build a very cheaper Dell Machine with the same specs. On first glance the Dell XPS 15, you could think that it has better specs and is cheaper, but on the TB3 side, it is just not as premium as the MBP.
If you need the four high-bandwidth ports or not is another question
But yes I agree, there should be a 15" more entry level machine, because not everyone wants to connect 2x GTX1080 TI, a couple SSDs and 10Gigabit-Ethernet.
As far as I know, the Snapnator only supports PD, no Data. So a integration into the MacBook Pro would be impossible.
The Power-brick would be a candidate for something like MagSafe, or maybe the Power-Cable itself
