If mobile devices somehow reach the point where they are much more powerful than the PS4 in 10-15 years, and you can use them to output full HD or higher resolutions on your TV, I could perhaps see them being the "next-next gen", but basically I can only see mobile devices becoming more like the consoles and adapting their functionality, rather than consoles abruptly disappearing. At the moment however, mobile gaming is a giant step backwards. Yes, you can make fun little games on those devices, and it's nice that they are portable, but people like to play AAA titles just as much, at home, on a 50 inch screen and with everything turned up to 11. That's not gonna go away in our lifetime I think. As for streaming games and all that shit, yeah, no, not gonna happen, unless in the next 10 years 80% of the world's population has access to fast stable internet, which is not possible since this would also require huge investments from governments in order to build the correct infrastructure, and the way global economy is going it's laughable to think that this is going to happen.
