Based on the previews, I think 4E is going to be a great game for me. I don't want to bother buying yet another version of 3E, a game which I think is growing quickly obsolete (heck, I never even bought the 3.5 core rulebooks, so why should I buy Paizo's books?). Also, I have never once purchased a Paizo product, and I have never felt that I was their target audience (they are far too obsessed with older-style D&D for my tastes). As such, Paizo's decision just means that I am even less likely to ever buy one of their products.
