A trademark for City Stories has been filed by Rockstar parent company Take-Two Interactive.
The North American trademark filing hints at a possible new Grand Theft Auto handheld spinoff.
Trademarked on May 15, the City Stories filing lists Liberty City Stories and Vice City Stories as related properties, according to GameSpot.
Outside of a new handheld release, the listing could point towards future GTA 5 DLC.
Rockstar Leeds developed both Liberty City and Vice City Stories, as well as Chinatown Wars on the Nintendo DS.
Rockstar is planning to release "substantial" GTA 5 story DLC later this year.
