Look, I wanted to know from WotC if there was movement on the OGL front and hoped they say something during Gen Con. So, goalpost-moving to "major" aside, they made sure to make mention of it in their stack of Gen Con-timed announcements via the podcast interview.
FWIW, I think it is pretty clear they have no intention of using the OGL (nor the GSL) for 5E. I think they will continue to handpick partners to work with for outsourcing (with varying degrees of oversight) much of their 5E content and keep the spigot at the steady, slow, but healthy (for their business model) stream that is currently being used.
If they develop some sort of license to expand the field beyond the current partners, it will just be a matter of tying them to certain types of products that require full content approval and allow for the D&D logo to be displayed.
It's clear they have no interest in having a full SRD and OGL in use during 5E. I also think we'll see more cracking down on those who try to do an end-around with the OGL intimating 5E compatibility. So far, I think it's only been a few websites with generators and wholesale use of actual 5E content that have run afoul of WotC but as it becomes more widely apparent they aren't going near the OGL, I also think more folks who want to publish 5E material will take more chances and cross some lines that may not yet have been crossed. We'll see.
