Looks like Kobold Press fired the first cannons in reply to OGL 1.1. Project Black Flag looks like it will be its own game system to divorce itself from the SRD.
I really believe all the big developers like Paizo, Kobold, AAW, etc need to get together and build a new generic game system that anyone can use. And so they can divorce themselves from the SRD.
Incidentally, I have sold off all my D&D books and will never ever run another D&D game again after 40 years. I am boycotting direct WotC products from now on.
Luckily I have most of the Pathfinder, Starfinder, and all the Pathfinder 2E books digitally and many physical copies to keep me and my group happy for years.
