Interesting that:
Goodman Games and Mongoose are already in.
Paizo is committed to 3.75, so they're out no matter what.
Green Ronin is off doing non-D&D material.
Basically, IMO, we are left with the Wizards changing the GSL for Necro, and only for Necro.
Not necessarily. Goodman Games are using the copyright route at the moment, and will go GSL when they are allowed. Kenzer are going the copyright route. If the GSL changes, both of these may sign up (sooner). And it is definately in WotC's interest to avoid companies from going the copyright route if they can. (Though, with Goodman, I think they're too late - aren't those products now shipped?)
I don't think Green Ronin have said "never" to the GSL - so perhaps these changes might bring them on board. Or perhaps not. Heck, even Paizo haven't totally burnt that bridge - Pathfinder might yet flop.
Finally, it has been pointed out on many threads here that the current GSL has the opposite of any intended 'quality' effect - it discourages those who would invest in a quality product line, but encourages those who might throw a product together quickly, make their money and get out.
Revising the GSL may impact on some, all (or none) of these. Regardless, I'm hoping it leads to more quality support products for the game (especially, at the moment, low level monsters and adventures).
