From member Justowen comes a news article about a new MOTU reference book for next year, because of the success of the Art of He-Man book and the mini-comic book released this year.

This one is about the original He-man and She-ra cartoons, including...

nearly 600 pages of fascinating story synopses, behind-the-scenes artwork, and trivia for every single episode of He-Man and the Masters of the Universe and She-Ra: Princess of Power. Written by He-Man and She-Ra expert James Eatock, He-Man and the Masters of the Universe: A Complete Guide to the Classic Animated Adventures also features never-before-seen Bruce Timm artwork and reveals Orko’s face for the first time!
He-Man and the Masters of the Universe: A Complete Guide to the Classic Animated Adventures is in stores August 17, 2016.
Should be an interesting read... just got to wait 8 months for it though.
