I'm not sure that I agree that D&D even needed a new edition. I could still have great fun playing under old, 1st edition, AD&D rules, and 3.5 is LIGHTYEARS beyond that system.
But both 3.5 ad 4.0 are now no longer possibilities, they are facts. But, still, I agree with you about Pathfinder, and if there is to no longer be publisher's support for 3.5 D&D, then Pathfinder is the best available choice.
I also agree that 4.0 is NOT D&D as it has been prevously known and understood to be. However, considering the ownership of the copyrights, it IS, by definition, D&D, whether we like it or not. And strange as it seems, even to me, I have actually been having a fair amount of fun playing 4E, even though the VAST expense of buying a new edition is about to threaten to put me in the poorhouse! (At least I'll be happy there while I eat my gruel and battle the cockroaches for a place to sit down?)
