This does not make any sense:
The new MacBook Pro machines will feature a flat-edged design, which Kuo describes as "similar to the iPhone 12" with no curves like current models.
The iPhone 12 uses a flat edge curved design. Unless he means they are going back to the 2006 MacBook Pro straight edge design, just with the current thinness of course.
I would find it strange for them to go back to adding more ports like USB A. I assume SD card reader maybe? But since upgrading to the 2020 M1 from my 2015 MacBook Pro, I haven't missed a single port. In fact, SD Card, HDMI port, older Thunderbolts were rarely, if ever used.
As for the Touch bar, I actually like it and it does not bother me one bit. Its usage I will admit is sparse, but so were the existing function keys on older generations, outside of volume up and down.
Considering I just bought my M1, I won't be an early adopter and will likely wait this one out for a few years. I am more likely to upgrade again next year Christmas, but go for an iMac instead. Hope they introduce a 32 inch screen.
One note I forgot to add, I will welcome the return of Magsafe. Although with 20 hour battery life on the M1, I rarely plugged in, but the charger for my 2015 is close to me and wound up in my feet the other day when I was stepping away from my desk and I pulled effortlessly. I don't think that would be same effect if it was the M1 with USB C.
