F* no.
This would have been like asking in 1999, "Will the next iMac have a floppy drive?"
Or asking in 2005, "Will the next iPod return to FireWire?"

I miss the over-the-air TV tuner in the late-1990's Performa (or whatever model it was).

I don't think a magnetic port that often transfers data is a good idea.
There's that crowdfunded magnetic USBC-to-everything plug, and I thought it would be really cool, like the Holy Grail of MagSafe-meets-USB-C adapters. I thought, this would be sweet, I could plug in an external drive and display and power, and none of it would come crashing to the floor if I tripped over the power cord (like what almost happened to me and my mid-2012 this weekend).
But then I thought, wait a minute -- when is my external drive not on the same table as my laptop? No, when I have my external attached,
I don't want it to randomly disconnect for any reason, and it's never located in a place that'll make it a trip hazard, either.
I'd be fine with regaining MagSafe via a simple power-only connector like Griffin's. But a magnetically-attached data connector? No way.
