The most time consuming part of running D&D has always been making the adventures. And I don't mean using the rules to design, but actually writing the stories and plots.You can't make time every time you play. It's life that doesn't let you to. I am not going to buy a game that is not simple and easy to run or design my own adventures. That, doesn't necessarily means that the players or the DM won't have options (simple does not equal simplistic). It just means that everything has to be very well organised and playtested before it goes to print.
You can spend as much time as you want on the mechanical side, or you can just grab monsters of the appropriate level and throw them together. That's easy. It was easy for 3e/PF and was easy in 4e.
If you're into the game, you're invested, you will make them time. Instead of playing the little timewaster mobile game or watching TV you'll do some prep. If you procrastinate, then the problem is one of engagement to the story, not the system.
D&D the RPG doesn't need to be extra-super simple and streamlined to compete with mobile devices and games and apps. It needs to be engaging enough to involve people despite those timewaster games.
