I'd be a lot more likely to check it out if it didn't have DnD on the cover. As it is, it bares only a passing similarity with the D&D/AD&D that I grew up with. And while some of the design goals are interesting, it just doesn't sound like D&D to me. Neither did 3e, and that wore really thin after a while. But from the start, 4th ed has sounded more and more like a heartbreaker fantasy, something that might sell a 10th of the volume if it was called anything else, regardless of the quality of the play. And yet, it would be free of the baggage that comes with the D&D title. It also wouldn't have to worry about fixing so many things that were never broken simply to shed itself of a few sacred cows (and yet, the 3-18 ability scores remain, even though they are a useless measurement now).
If this is starting to sound like a screed, I don't mean it to be. It's only that the farther the game wanders from its roots, the less reason I have to be loyal to the brand. And right now, Savage Worlds out 4es 4e as far as I'm concerned, so I'll stick with that. If I need a D&D fix, I have my 1st/2nd ed books, which is really the experience I want to be playing anyway. ::shrug::
