The notion that the OGL/GSL issue is a divide between "creative types" and "corporate types" is absurd. The D&D team at WotC are game designers and game players. Whether or not the legal team decides to make D&D open doesn't in any way change the direction of the D&D game itself.
Again, I support the OGL. I want 4E to be open. And I respect that, for some people, if it's not, that's a big enough issue not to switch. But it's a big enough issue on its own; let's not go making it a bigger deal than it actually is. And what it's not is the end of D&D as we know it, or a return to the failed policies of TSR, no matter which way the decision finally goes. It would be bad for D&D and for the industry. But it wouldn't be fatal.
