It seems clear to me that they're going to incorporate the exact same Mag Safe charger as they did on the iPhone 12. Same magnetic paddle, but it will attach to the lid or the back or something.
In the case of the 16", which draws 96W at full bore these days, more than six times that. I've heard speculation that the new MBPs might not wirelessly charge themselves... but could have an integrated wireless charger in the palmrests for iphones/etc.
Hope it's the bottom. Then you can "dock" your MBP without any latches. Some people might make a desk or tabletop that would allow the On the screen back would look bizarre.
Now imagine if MagSafe could also be a data channel...
