That's because you lack imagination:
- 16TB SSD (my 8TB is really too little, I need to get rid of my extra 4TB+ external SSD drive as mentioned before)
- FaceID!!! (so annoying not to have it on MBPs, it wastes a lot of time having to type)
- remove the notch!!! (so annoying)
- 24h battery (better but still room for improvement)
- Thunderbolt 5 (that should be the case)
- Wi-Fi 7/802.11be (40 Gbps) (should be the case too, rolling out end of 2023)
- SSDs in that capacity are still incredibly expensive, regardless of form factor. External SSDs are incredibly convenient, lightweight and take up very little space in my bag. I have a 2TB Samsung 970 Pro in an M.2 external enclosure and it flies when transferring data to and from my MBP.
- To accommodate FaceID, the lid of the Mac would have to be thicker and the notch possibly enlarged to accommodate the additional sensors. That would increase the overall bulk and weight of the machines.
- a 24 hr battery would require significant improvements in battery technology without increasing the total watt-hour capacity. Keep in mind that there are FAA-imposed limits for laptop battery capacities, so most existing battery designs that could provide 24 hour battery life would far exceed those limits and limit the ability to take your laptop with you when traveling (whether for business or pleasure).
- WiFi 6E would be the better option at this time for a few reasons. Wider availability, increased performance even connected to WiFi 6 routers, lower cost due to being an established protocol instead of a new one, etc. With a WiFi 7 part, you'd be paying a premium for technology with limited usefulness at present.
