Take-Two Interactive, parent company of Rockstar Games, has announced that Grand Theft Auto V has shipped 33 million units worldwide by May 1st 2014.
Even if Take-Two talks about units shipped and not sold in its fiscal year 2014 report, the number is gigantic. With this performance, GTA V is now the sixth best-selling video games of all time after Mario Kart Wii, Super Mario Bros, Minecraft, Wii Sports and Tetris. And all of this under a year from the game´s release date.
Take-Two had also announced that a new game is currently under developing at Rockstar Games studios, and is fair to say that this one can be an Xbox One and PS4 version of Grand Theft Auto V.
