If 4th Edition didn't use the "D&D" moniker...

Well, yes. The rose, by any other name, and so on.

Very probably. I'm a bit of a collector of different rpg systems and if I got the news about it being released and the first reviews were good, I'd buy it. Even if it was just for a good read and enjoying the art - which promises to be excellent.

As others have said, if everything else was the same except the D&D brand (the publicity, rules revelations, the particular developers, etc.), then definitely I'd buy it.
