Kenzer is most certainly not going with the GSL.
Alright, so what would be a better way to divide the starting field? How about:
In WotC's camp
Kenzer
...
Out of WotC's camp
Green Ronin
...
My intention isn't merely technical (who's signed the GSL) - I wanted to start a thread where we could see who was going to support Wizards and 4E, and who is choosing not to.
With the new announcement by Wizards of the Coast that publishers like Necromancer Games will be able to support the new Dungeons and Dragons 4th Edition rules, Necro is going 4E! That's right, "Fourth Edition Rules, First Edition Feel"
