Perhaps I came across as aggressive initially, however I suspect when something seems so at odds to what I take as sense and data - was the original poster doing it for discussion instead of it being their actual position.
There is still a desire for consoles, and expensive ones still sell. In many ways the power, specs, and sexiness of the new consoles appeals to punters.
If these consoles cost £50 they wouldn't be as powerful and wouldn't be as desirable.
Skoda sell a lot of cars, yet they aren't as desirable as BMWs. The latter costs more, for a reason. Which then have far more loyal fans. Consoles are not much different.
Merc/BMW - PlayStation and Xbox.
Of course if the original poster is right then Stadia should be selling through the roof.
It's actually cheaper.
Yet he goes on to then discuss the merits of PC gaming!
High specs Pcs, even further ahead than your consoles. Costly to repair and fragile. Suddenly you've gone from a PS4 Merc to a PC Ferrari.
I think there's room enough for every type of car in the gaming world. Except Fords, which drive like ass (see Stadia, above).
