I don't believe that is what Snarf is saying in this post.I find it pretty sad that the biggest thing in D&D in a long time is commonly looked down on as “not D&D”.
If I read it correctly, they are not saying it is not D&D. They are saying "It's not the typical D&D game you will find in LGS's or at home games." And I agree. It's D&D, but D&D run as a show, with higly talented professional actors roleplaying their characters. With someome that can spen dozens of hours a week preping story and encounters, with almost unlimited budget for minis, terrain and ambiance.
