I've been waiting for this! The 'art of' book as well as the official novelization have been announced for Godzilla: King of the Monsters! The novelization comes out same day as the movie, well the art book drops a few days later.
The most controversial, and unquestionably most popular part of the Godzilla 2014 art book was the various radical redesigns that were solicited to bring a fresh perspective on Godzilla's design. I can't wait to see the Rodan, Mothra, and King Ghidorah equivalents of Godzilla with those porcupine spines!
