The trademark seems to suggest that Granblue Fantasy: Relink is the final title for Cygames’ PlatinumGames-developed PlayStation 4 action RPG Granblue Fantasy Project Re:Link.
Here is the old logo for comparison:
News on the game is scheduled to be announced at Granblue Fantasy Fes 2018 on December 15 and 16.
In other trademark news, Sega Games trademarked “Nanatsu Iro no Romance,” or “Seven-Colored Romance” (the kanji for “Romance” actually reads “Boukendan,” or “Adventure Story,” but it is read “Romance” in this case), and Square Enix trademarked “Slash Field.”
Update 11/27/18 at 8:10 p.m: Added the logo for Granblue Fantasy: Relink and updated the reading for Sega’s “Nanatsu Iro no Romance” trademark. Links to each trademark have also been added.
