They annonced it a minute ago, probably like in the spring or summer when there were rumors of a part 6 starting to float around
Idk what they can do to keep people like us invested when it goes to next gen but I get why they expanding that shit. Its cause they let part 5 get too big, they put all that time into updating the shit instead of working on the next game so now they probably dont got enough fresh shit to do a whole new online mode.
they should of saved the Casino, the night clubs and some of them other big ass updates for a new game
