How much new stuff for 3e SRD and the 5.0 SRD are you expecting? Is anyone making content for PF1? When was the last Mutants & Masterminds release?
Consider that the openly stated goal is that OneD&D will be backwards compatible with 5e, and that OneD&D is intended to be an evergreen edition.
Further consider, that the 5.0 SRD is in the wild, and 5e-alike offering(s) already exist.
Now we see, that the 1.0 OGL being killed, is actually critical to Wizards.
