Twitter user @VoltySquirrel (via Gematsu) was the first to tweet the pictures, and also stated that the game could see a reveal sometime within the next year.

@VoltySquirrel later said that there wasn’t much revealed about the game, but did say there might be a console release, and the art style will be “sketchy while still being 3D.” 

For fans of Mistwalker’s past games, such as Blue Dragon and Lost Odyssey, this is great news. Fans have been waiting for a new JRPG from Mr. Sakaguchi for a long time, so any news about a new game is good news!
