Tavern Chat Twofer - The Great Kingdom Documentary & Long Lost Mystara Manuscript

Dueling documentaries of the legacy of Dungeons & Dragons left only one standing. What is the latest update from The Great Kingdom, and what can those that backed "the other" documentary do to, if not be made whole, at least get something of value?  Jeff Grubbs long lost Mystara World Setting manuscript, originally written for AD&D 2e (and replaced by Karameikos: Kingdom of Adventure on the TSR release schedule), with setting appropriate kits and such, will be released at the Piazza later this year with the permission of WotC.
