I don't think so.
I haven't seen the concern about that particular point. I mean, why else would Morrus and a bunch of other publishers be rushing out unfinished product so it's "published" before the 13th then?
In any event, I don't want to derail the OP here too much. At the very least, if you have a physical copy of a game or a PDF saved locally there's nothing Hasbro can do to stop you in any reading of the news.
As someone who is just starting in the industry:
There are 3pp who intend to pull their entire catalogue down after the 13th because the OGL 1.0a being "Deauthorized" may mean that all 3rd party content becomes 1.1a whether you publish something new or not. That Wizards is going to go after anyone and everyone who has anything published and steal their work if it's still being sold after the cutoff date.
Whether they actually -can- steal previously released work or not is a question. The chilling effect on the industry is not.
As for your trouble, Dave2008... I would suggest keeping D&D Beyond. And buying more WotC books over time to improve its functionality. And if people are willing to put their content onto DDB to become interns for Hasbro who -might- earn a little cash when the company isn't stealing their work, buy that, too.
But also, please, support your 3rd party publishers who have no real economic choice but to move on. And particularly keep an eye on A5e, which may get De-OGL'd. And if it does, it'll be D&D without the seal of approval of WotC and you can probably use it, too.
Personally I'm hoping we do get rid of the OGL for Level Up, and I get to produce tons of content for it, going forward. It'd be great to get to continue to talk to you about it, -and- continue talking about D&D stuff in general that you can also use in the system!
