I got my PDF today, and thank you. More on this soon, but it is a cleaned-up version of the 4th Edition books. Functionally identical except for language choices and tone, and many small improvements. There are a bunch of pages of new material too, though page numbers have been preserved. Two-column layout. At first glance, this feels like those still playing with older books won't notice many differences and can keep playing with those with newer books. Nice job.
