For those who haven't been following Chaosium closely these last few months, the new version of Masks of Nyarlathotep has been released on PDF as of today.
https://www.chaosium.com/masks-of-nyarlathotep-pdf-1/
Buy the PDF from Chaosium and you get a coupon for the price of the PDFs off the physical slipcase. You can also buy from DriveThruRPG but you don't get the coupon.
Happy gaming!
