Inductive charging is horribly inefficient and it would be a huge pain to have to lug your six-foot-radius inductive charging transmitter around with you. So that's out.
Magsafe went away on the Macbook because the designers did a bunch of testing and realized that the USBC connector yanks out of the socket almost as easily, unless pulled at an angle, and in that case, the Macbook is light enough that it tends to pivot before it gains enough momentum to fall off a desk. That and, everything in the Macbook is solid-state. The risk of damage from tripping over a cord is less, while the risk of damage from dropping it at standing-height was never addressed by magsafe in the first place.
What remains to be seen is, will they refine the design of USB enough that the extra weight of a Pro machine doesn't interfere with cable detachment, and, will they be able to charge a Pro-level battery acceptably fast enough by the USB quick-charge standard. If one or both of those questions come out "no", then you'll be seeing a magsafe connector, or dongle, on your new Macbook Pro.
Your history lesson about Apple removing the floppy drive is just a little bit revisionist. All those devices you mention that eclipsed the 3.5-inch drive really only became usable once the USB standard got entrenched, and the iMac was one of the biggest reasons for that. Remember when ZipDrives needed a special driver, and ran off the parallel port? Or off the SCSI port? Same with SyQuest drives. They were SCSI- or IDE-only for a very long time. What was killing the floppy before the iMac was all those ZipDrives and SyQuests AND the rise of dirt-cheap home and small business LAN hardware, and the ever-cheapening cost of CDs and CDRs. Ubiquitous USB came later. Let's not put the historical cart before the horse
But anyhoo... Thunderbolt. I'm glad you mentioned that. There's some good news on that front: https://www.cnet.com/news/thun...
Don't think of the new MacBook Pro as having a bunch of small-size USB ports, think of it as having a bunch of Thunderbolt 3 ports. That's one port for supplying data in and out, at massive speeds, including multiple displays, and it's daisy-chainable, and it supplies power!! Of course Apple is all over this! What else would they be doing?
That said, if they eliminate the headphone jack, I'm going to have to drive down to Cupertino and slap some people around.
