I have a question, too. Where will we buy it? The Design Mechanism shop or only on drivethruRPG? I'm asking because I'm not a fan of drivethruRPG. They watermark/protect the PDF's because of piracy, which is fine. But it hinders the user making bookmarks which is an absolute deal breaker for me. On the other hand it must be an "upload" feature from the publisher that is defaulted to be active because not all PDF's have it.
I mean I want to organize my own bookmarks in the PDF when the book is bigger than 100 pages, because that is the whole reason I'm buying PDF's in the first place!
