Dungeons and Dragons, 4th edition

For the record, I do not yet have an opinion on the forthcoming 4th edition of D&D. It's largely not relevant to me, since I'm not roleplaying enough and I'm not a big fan of straight Tolkien fantasy, but I'm curious as to what has changed over the years.

I know one of the design goals aims to incorporate more online experience, and I've heard that some of the rules aim to include more indie/narrativist/story-oriented/player-driven play that's at the bleeding edge of the definition of roleplaying game. Do I think D&D is going to be a hippy-love-fest game? I doubt it seriously. Do I want to have the option for more play, less single-player driven play, and severely reduced prep time for the GM? Hell, yes.

I don't think D&D can become the kind of game I want to play, and I'm okay with that.

UPDATE: Purple Pawn reports that the books have been leaked onto the net a week before release.
