I think Nintendo is done making dedicated consoles. Hybrids like the Switch will be their future.

I just cannot see Nintendo making a console that matches the hardware performance of the current generation's PS5 and Series X. They have always been behind when it comes to hardware and the Switch was no different.

Sony couldn't compete in the handheld market and so I don't believe we will see another PSP/PS-Vita as a PS5 companion. Nintendo will continue to be a solid manufacturer in the handheld/hybrid console market.
