Fake.
Doesn't mean anything.
The 2405 thing is sad. Nothing GTA V related is going to happen in the middle of Max Payne 3 releasing. That's stupid.
How the fuck does that mean the game is 87% complete? Where the hell did you pull that number from? And just because they talked about crews doesn't mean anything is actually done with V. It just means they have a starting point already. They still have to code the whole multiplayer system for the actual game. And no, Rockstar didn't say Gang Wars would be in GTA V. That's Max Payne 3.
