Why does everyone (on this thread) think D&D needs to be "simplified" anyway? 3.0/3.5 is already a streamlined machine of beautiful efficiency compared to all previous editions, with their "bend bars/lift gates" rules and stuff. Man, you give people an inch....! 
In any case, D&D was never intended to be some kind of "perfect generic fantasy RPG". The d20 system may be generic... the OGL may be generic... but, ever since they made the decision in D&D 3.0 to officially make Greyhawk the "default" setting, D&D has been some game about some weird-ass fantasy world with too many monsters and races and classes somehow coexisting together. :/
This is how they make money... they keep adding new stuff. And this is how they reinforce their D&D "branding"... they keep adding new stuff that they can COPYRIGHT/TRADEMARK, i.e., focusing on the displacer beasts and beholders and mind flayers instead of the "generic" things like goblins and ogres and dragons.
Personally, I like heavily variant settings, and I try to make my campaign worlds pretty different from Greyhawk, but I think I understand some of the reasons why TSR emphasizes Greyhawk. Anyway, I don't need to see D&D become some "generic fantasy" RPG. As far as I'm concerned, D&D can remain its weird, screwy self, as long as the rules leave open the options to make up your own campaign worlds, and as long as the d20 license lets publishers publish their variants.
