A new redesign for Killer 7 and No More Heroes developers, Grasshopper Manufacture, has revealed that the developer is currently working with Square Enix.
A section listing their past a present business partners mentions a Square Enix project, labelling it as “???”. The list also mentions the horror game they’re working on for EA as well.
The list on the site mentions all of the following.
ASCII CORPORATION -> The Silver Case
CAPCOM CO.,LTD. -> killer7
ELECTORONIC ARTS INC. -> Untitled horror game
MARVELOUS INTERACTIVE INC. -> Contact / No More Heroes
NAMCO BANDAI Holdings inc. -> Samurai Champloo / Blood+ One Night Kiss
Q ENTERTAINMENT INC. -> Untitled horror game
SEGA CORPORATION -> Shining Soul II
SPIKE CO.,LTD., -> Michigan: Report from Hell
SQUARE ENIX CO.,LTD. -> ???
TECMO,LTD -> Fatal Frame IV
UBISOFT ENTERTAINMENT -> No More Heroes
As for all the recent rumors, I’m guessing on an E3 reveal if they are in fact working on a game for Square.
