I still think that it's a red herring, that the leaked schematic is an old design or whatnot. I believe the redesign will keep the trend of 4 USB-C ports. The iMac is an example, Apple went completely USB-C.
Or, Apple could be doing a "Special Edition" MacBook Pro, maybe a last intel version, with the leaked schematic setup, to commemorate the successful transition to Apple Silicon, as the "last hurrah" for intel MacBook Pro. I'm sure many people will still buy it, which means more money for Apple. Meanwhile the "next gen" MacBook Pro will remain USB-C.
It's really difficult seeing Apple backtracking a lot here. Plus, dongles = more money for Apple. The MacBooks has gone USB-C only for how many years now? And it's not like people stopped buying them.
The clutter/dongle excuse is weak as most Windows Ultrabooks are doing the same thing. Most premium ultrabooks use dongles as well, only having USB-C, with maybe USB-A at best. Heck, I have an old Lenovo laptop, and it only has two USB-A port (one for the charger) and a micro-HDMI port. So regardless, I would still need a dongle or specific cable, and this is like from 2015 or so.
I'd rather see put more USB-C ports, like 6 total, 3 on each sides. There's plenty of room, especially for the 16" version.
