Well since PS5 is supposedly going to be more of a streaming service than a physical platform, just make a portable machine capable of connecting to that service. It doesn't need exclusives or anything. Just make sure it can play the entire PlayStation library. Make it a portable PlayStation with no compromises, smaller screen and limited battery life aside. We don't know how the PS5 will work, so I'll leave those details to Sony, but basically their next handheld should itself be considered a PS5.
They got halfway to this idea with the Vita, but stopped short of going all-in.
