Arguing the specifics of the word "Console" and other semantics do not magically make the reality any less there.
Console, in this frame of reference, has always referred to the variously shaped boxes that people smack down in front of their TV's, grab a controller, throw in a game, and play. Yes, you could probably call the other devices such as an Ipad or Ipod a "Console", if you were feeling ridiculous and wanted to make an entirely pointless point (Yes, i know what i just typed.)
I mean, this is up there on some of the most absurd logic I've ever seen. He's saying that because you can call technically call an Ipad or Facebook a gaming "console", that the traditional consoles have succeeded? Thats like saying Beta succeeded because VHS won the video tape war.
Of course there's always going to be an Ipad, a facebook, or a cloud. Its a distribution method and a platform, we can't just absorb games from some infinite ether. Though, with this guys logic, i suppose if we did figure out how to do that, he'd call the infinite ether a console.
