One of the things I advocated long ago is that the core D&D rules need to have some... switches and power levels that the GM can change that effect the basis of the campaign and can take it from high fantasy low magic items (most fiction ala Wheel of Time), to Pulp Action (Conan, Fafrhd, etc...) to the standard gaming default of D&D.
Don't think it'll happen mind you because the game system is so far up it's own behind that it really can't pull out now. It'd be too different. Since 3.0, by default, the only genre D&D has been good at emulating is the D&D game, not even the D&D fiction.
