Of course, so many publishers were releasing 5e material under the OGL without a 5e SRD or simply using copyright law that the genie really was out of the bottle.
Wizards did find a way to get some monetization from the new SRD - The Dungeon Masters Guild(powered by DTRPG) is their online 5e store which includes 3rd party publishers. It's 5e's D20 license and allows the use of Forgotten Realms material (so long as you let WotC do all the selling)
I expect we'll see a real surge in 5e releases now.
