I think one thing you guys are ignoring about the success of netflix - and the potential success of stadia - is that its not just the carrot of netflix being one sub, a wide variety of content within that sub without any hidden extras, and that sub works on any of the devices you already own and you can access it in any way you feel like entirely at your own conveinence.
Its also the stick of cable companies being stupid greedy assholes, and that netflix sub letting you get away from all of their bullshit.
Sony and MS are stupid greedy assholes, and they have utterly fucked up huge aspects of the value proposition of owning a console in the first place in their chase to be more like a cable company.
Don't get me wrong, Nintendo are stupid greedy assholes too, but they're working in an entirely different asshole space.
