Control panel will forever stay in the right corner on the X because of the swipe up to do things so don’t expect that to change. Also I came from 3 years of a plus model it only takes about a day or 2 to get used to size of the phone. Then once you go back to pick up a plus model you realize just how way to big it actually is and that the iPhone X is the perfect size.
I was thinking more about a possible X plus. The top right corner would be a quite a bit further away. It'll be interesting to see how they manage it.
