A short time ago we reported on a new Pikachu-focused Pokémon title that was apparently in development at Game Freak. We then heard that the game would place the player in the role of a detective, with Pikachu acting as a partner who helps solve crimes.
We've now heard that Nintendo has filed a trademark in Japan for Great Detective Pikachu, which sounds like a good match for the title in development.
Serebii Updates: New trademark discovered: "Great Detective Pikachu" (名探偵ピカチュウ) http://t.co/oV6DIIRILJ— Serebii.net (@SerebiiNet) November 7, 2013
Of course, this doesn't mean that it's the final title — trademarks are filed all the time which never end up being used — but it does at least suggest that Nintendo is looking to cover all the bases when it comes to giving this new outing a suitable moniker.
