None of that stuff will happen, honestly. The first leg of the tour went fine, but the second one was a plain disaster. Who will honestly play a smartphone game a year after an album came out? Not many. Who would read a novel about a plot that already in lyrics form was cringeworthy in a lot of places? Not many.
DT aren't screenwriters, or authors. They are musicians. The earlier they return to what they are best at, the better. There is so much music to explore that they shut out (jazz, acoustic), it's an utter waste of time to go The Wall when they so clearly aren't good at it.
