According to a rumor started on a Japanese blog, Square Enix is bringing the DS title Final Fantasy: The 4 Heroes of Light to the 3DS. Whether or not the game will be a simple port of the DS version released in Japan back in 2009 or an entirely new game is unknown. 

The site also claims that Capcom is working on a new Monster Hunter title for the system which is expected to be announced at the Tokyo Game Show in September. This rumor seems believable since Capcom EU boss David Reeves has hinted at a Monster Hunter game being in development for the 3DS.

Lastly, Sega is rumored to be developing a Hatsune Miku game for the 3DS. As of now this is just a rumor. We’ll have to wait and see how it all pans out as the Tokyo Game Show approaches.
