Linda Codega of Gizmodo confirmed D&D Shorts's leak. Linda thoroughly vets information, so that makes me feel pretty confident about the second rumor.
EDIT: I somehow skipped from page 1 of comments to page 3 and missed that Linda's response was already up here. Sorry for the repeat.

Mark Seifter here! Even more strangely, we have you covered there too at Roll for Combat, with our (free!) dungeon race and our (not free) enormous dragon race and class.
