1st Edition AD&D wasn't released OGL, either, and yet there is a thriving ecosystem of retro games and clones without incurring any C&D's from WotC.Unlike 3.x and other earlier games it can't really be 'cloned' in d20, it's own GSL is very restrictive, so no one is going to be able to pull a Pathfinder and basically publish the SRD as a competing game.
