Tip of the hat to ENWorld for this piece.
Evil Hat has released the first 25% of the first book of the upcoming four book series - Designers and Dragons. Yep, that little (huge) book that came out a few years ago is going to be re-released in a four volume series.
The TSR section is about 100 pages (and free) and the preview also includes the full index - Volume I is going to be over 360 pages.
I seem to have a lot of reading to do...
