Hey there pvoce,
Thanks for your interest in DD and welcome to the forum
A couple of brief answers for you:
Yes, DD5 is still in development albeit it has been slowed mightily by life circumstances. That is: I'm just a regular guy, getting slain every day at my day job, raising a family, and trying to study too. It is still happening though, and one way or another V5 will get done. The most recent, modest steps include quotations and samples from a letterpress printer, continuing art production, and discussions around supplement development with a couple of interested writers. So... stuff is still quietly happening, but not in a hurry.
Regarding the OGL/licensing. Yes, that is a big deal. The torpedoing of trust in the OGL means that OSR products like DD are more or less forced to republish under alternative arrangements. So, DD5 will be published under alternative arrangements. What will those arrangements be? Truth is, I'm not 100% committed yet. I have been waiting to see if a suitable license would appear under Piazo's black flag initiative, but that hasn't happened yet. There are a couple of other options, including the no license option, to consider. But end of the day, I haven't decided which way to jump yet. Happy to hear about options in that space...
I hope that helps!
