It was a shit take, traditional home consoles were never under severe threat by mobile/browser/social gaming. On the other hand; dedicated handhelds are all but dead and gone. Look at the collapse in sales between the DS/PSP era and the 3DS/PS Vita era, that's where the real hurt arrived.
But, yeah, "console gaming is dead" is even more hilarious in retrospect. I have a lot of experience with dead markets and platforms, seeing as how PC gaming has been dying since the early 2000s.
