The time might be now. Canon may see this in their demographics. It's likely that Canon recognizes their future customers grew up with smartphones and don't use menu based systems. They consider them archaic and will not buy a product that doesn't have a modern user experience. Which explains why Canon might choose to support both interfaces for a while.
I was reading the manual for the 90D, and I learned that you can press the Q or Info button in the Menu to switch to the next main tab, you learn something new everyday haha.
