The cameras themselves wouldn't rotate, just the placement of them.
Also I'm pretty sure that the sensors are square anyway; I imagine it's just the software cropping photos one way or the other.
I wonder if the new placement would be better for 3D capabilities for AR etc
If the sensors were square, and they aren't in almost all digital cameras on the planet, Apple could simply add an 'Orientation' button on the camera app similar to the 'selfie' button.
The 3D idea holds because I would imaging videoing in landscape is more in line with the VR headsets and how they are used.
