Much of the information which has filtered through here to the community has been from reports of snippets from the panel held by WotC's Mike Mearls, Jeremy Crawford, and Chris Perkins. Now, the whole panel has been released in full by Gaming and BS RPG Podcast. It's a couple of hours long -- "Recorded at Gamehole Con 2016, a tabletop gaming convention held in Madison, Wisconsin, this bonus episode features Mike Mearls, Christopher Perkins and Jeremy Crawford from Wizards of the Coast. This is the unedited seminar that they hosted. They discuss Volo’s Guide to Monsters, the differences in settings and the design approach to each one, field Q&A’s from the audience where someone asks about their own home rules that they use in their own D&D games."
