In my opinion the second best console is the PS2. I love Nintendo but they're more like toys than hard core gaming and entertainment machines. PS2 up until PS4 was pretty much the pinnacle, but I think the way PS4 improved upon it is the development platform, and the online experience (which even so does require some improvement). I still play games on the PS2 from time to time and they still feel viable as offline single-player experiences and I could imagine development for the PS4 could continue for 20 years or so and still be producing great and relevant games.
Where to from here? VR is one obvious route but may I suggest a HN-friendly alternative? Hows about selling a more open system that allows end-users to tinker and contribute themselves? I think in order for this to be viable in terms of protecting the profitability and stability of the ecosystem there are some business and technical challenges but I would love to see them take this direction. They've dabbled before with the Yaroze system and Playstation Linux … both had their business operational issues but hardly insurmountable?
EDIT - can't respond below any more so I just have "one more thing" to say:
> PS4 is famous for being the cheapest sony home console relatively speaking
and what exactly is the problem with that? This is a feature not a bug. The PS3 was a novel system with exotic hardware but it suffered from some very serious flaws. It's reliance on proprietary technologies meant it was harder for developers to work with. It never took off as a result and is little more than a footnote in the lineage's history. A learning experience if you will.
Surely an extension of making something easier for professional developers to get to grips with is making something that hobby developers (and other classes of creative) can get to grips with?
