Over 6 attempts at home consoles Nintendo have only beaten the worst selling PlayStation home console once. With 2 attempts Sony has beaten the worst selling Nintendo Handheld once. Neither has any chance of happening, Nintendo needs portability to sell, PlayStation can't compete in the portable market.
There isn't enough time left for this to change. Dedicated console hardware will begin to decline over the next couple of decades.
5G (and whatever comes after it) streaming is the future of handheld gaming, with the size of the device and battery not limiting power in any way. Playing games at 4k/60fps wherever you are while having great battery life. Every single game you own being at your fingertips with no worrying about storage. One device that can play PlayStation, Xbox, PC and Nintendo games.
