I'm not sure if this model is going to be sustainable. Games as service and the proliferation of suscriptions will eventually burn people out, not everyone has enough money to pay for all the subscription entertainment demands nowadays. The fact that, after years of paying for stuff you still don't own anything is just the cherry on top.
Who are you trying to kid? If anything, it is going to continue to grow with streaming being the main focus moving forward and digital games being the norm instead of physical. This is why Gamestop is going out of business, PSN is taking their pie.
