Even though something like Nintendo not making more consoles, is years aways, it's also true that streaming is a reality.
That doesn't mean that Xbox, PS and Switch (?) will have to become a mere stream subcription.
If there's one thing that people love is to get everything in a single place and be easy - if not instant - to use.
Then, the future might just be that future consoles evolve and become more like the go to device… or devices!
Whose to say that in the future, a console will be a stand alone device?
Imagine a console that can be separated so it can work with several TVs and you can either put the game card/disk in those parts or even stream through those parts.
Imagine if you can take a part of a console, plug it into your PC, laptop or smartphone and stream the game to such devices.
A stream only future for console manufacturers is far from being the only option.
