I'm not up for the latest MBP models but expect once they make a true Pro again including 32GB I may upgrade. Meanwhile I could benefit from a pair of hubs for both home and work, and am considering a 4K or another UW QHD+ display. I don't buy new displays yearly so t would be along the lines of a 34-38" UW or 4K...possibly with TB3/usb-c inputs included. Are there tb2->TB3 adapters that will work with degraded bandwidth and sans charging so I could, for example, pick up a pair of TB3 hubs and displays and use with my 2015 via TB2 for the time being? Protocol should be backward compatible but it's a lot of $ without confirmation.
