I think we will get PS4 Pro like specs on the next Switch if we are lucky...4k at 120 on a portable? Maybe in 2028-30. We don't even know if the PS5 will run graphically intense games at that framerate at 4k.
But even a "PS4 Pro" spec level Switch 2 would end up being much more powerful than a PS4 Pro, being a modern Nvidia chip on a newer node. I know we put a lot of this stuff out here for just comparison sake, but going by just numbers a Switch 2 would run circles around PS4 Pro if its the targeted metric.
