While I don't agree specifically with what this guy is saying, I do agree with his overarching concept.
What Nintendo achieved with DS and Wii (and MS later with Kinect) Apple and Facebook are, by and large, stealing away.
What chance there is to hold onto this market is related to creating novel experiences that you can't get on your tablet / smartphone / laptop like Wii and Kinect offers. Nintendo for reasons beyond me are leaving a lucrative market they created (motion gaming) to go back to a modified standard controller. If Sony & MS follow suit, then I think the market will lose all the progress that the last two generations made in gaining a wider base and revert back to just gaming enthusiasts. A market that probably cannot sustain itself at the level that it's enjoyed for the last two generations. Especially if Apple continues to steal 'mid-core' gamers.
