If the poster is correct, we’re looking at a Spring 2013 release. And again, if the poster is not a fake, then it looks like the PC and Wii U user bases may be out of luck, as the poster clearly only shows the logos for the Xbox 360 and the PS3.
Because the poster is European, however, the specified season could be for the European market only. The last Grand Theft Auto iteration, though, was released simultaneously worldwide, so it’s not unreasonable to expect the same launch from the fifth Grand Theft Auto.
Whatever the case, Grand Theft Auto 5 could use some publicity in light of Hotline Miami taking away much of its criminal shine.
