There's already been enough talk by the looks of it (if 17 pages are anything to judge by), so I'll try to keep my own thoughts brief. Firstly, I think this is a stellar idea - and a big nod to your fans, it reminds me of the way game developers used to conduct business back in the beginning of the century. Direct contact with the playerbase, as opposed to dry, corporate walls of text.
While one of my dreams has always been to see a Planescape 2, Baldur's Gate III or, heck, NwN 3...I have to say, I fully realise they are quite unrealistic.
