On December 21, 2003, one week after it registered GTA: San Andreas, Rockstar parent Take-Two Interactive registered Grand Theft Auto: Bogota, Grand Theft Auto: Tokyo, and Grand Theft Auto: Sin City with the U.S. Patent and Trademark Office. Since neither Take-Two nor Rockstar are officially commenting, it's anybody's guess whether the three GTA titles are potential monikers for the fifth official Grand Theft Auto game, future installments in the crime adventure franchise, or merely decoys.
