First, those people have to buy a WiiU or a Switch.
I can´t see "COD kids" or "GTA kids" asking their parents to spend $350 with this.
honestly think they don't have to.. i think the userbase has transitioned between the systems, but now alot of people that 'dropped out' are going back..
Time will tell though :)
