They don't have much time anyway, I think dedicated gaming hardware will largely be gone in 15-20 years, replaced by streaming services through Fiber Optic or other high speed internet connections and games that can be streamed from one's phone onto any display in their vicinity. By then the processing power even in a phone will be able to produce extremely high end visuals and every modern display will be a smart display capable of receiving a video signal from a smart device without needing a wire.
All you'll need is a wireless controller that the phone can sync to.
