Maybe. Or maybe not. Time will tell, I suppose.... So the crowd that would need to adjust would be those "in the know"... which is probably the crowd more likely to adjust. ...
Personally, I think the ultimate solution to this is quite simple: square source videos. Than you can crop to whatever you prefer -- and re-crop later, as desired. Seems to me the only technological hurdles to this are device capacity and bus speed; there's no reason at all that the cameras couldn't just capture a square instead of a rectangle.
Because the space isn't all wasted. My belief is that even if Apple puts all three rear facing cameras in a single row, there will still be a gap between them, roughly in the middle of the camera bar. That gap will be there to accommodate their future plans for an under-screen FaceID sensor and front facing camera.why cant the 3 lenses be in a row? why's it have to be so ungodly ugly with a ton of wasted space in the middle?
