I think there will be a physical PS5/XB2 ... but it will also start to become optional by next gen whether or not you want to own hardware or not.
There won't be a PS6/XB3/NX3 or whatever, upgradable or not because 1 gigabit internet will be standard by then and games will be able to be streamed even in 4K+ resolution.
If Netflix decides for example to offer a gaming service where you can buy whatever game you want, but you don't have to pay $400 for the hardware, and you can run games on high effects that evolve over time ... the Sony/Nintendo/MS model is going to look really, really badly outdated, but Sony is already test driving this idea with PS Now.
