Wizards/Hasbro has this idea that many people don't play the game because they haven't marketed it more towards them. Marketing has nothing (well, almost nothing) to do with it. People look at it and see dozens of books around a game table and think to themselves "Do I really need to buy all this just to play a game?" And gamers can argue or explain that all they really is one or three Core books all you like behind your stack of "optional" material. You know they're thinking to themselves, "So why don't any of you have just those books??"
Mike Mearls mentioned a few weeks ago that a LOT more people try D&D than we think (or something similar). So D&D doesn't have a problem attracting an audience, it has a problem retaining one. And they know it.
