The irony is that much of what he said is the same "Dungeons & Dragons" experts were saying roughly 20 years ago when asked about what makes a good RPG campaign. It does make sense... but it doesn't work in the long run (again, look at the death of pen and paper RPGs for an example).
Episodic content will not only strain the gamer's wallet, but will also lead to an exponential increase of individual releases (instead of releasing one game every two years, you get one new episode every two months - just an example).
At the end of the day, the saturation will mean that marketing will solidify its role as the main seller element (it already does most of the job), as the most commercially supported titles will overshadow the niche titles - much like it happens with television already.
This may actually be the future of gaming, but I personally hope it won't be.
