Fans are what they are, and they're nothing if not excitable—especially over the object of their devotion. Some fans on the GTA Forums speculate that Grand Theft Auto 5 will make the cover of GameInformer next month based on absolutely nothing apart from their undying expectation to see the game in any form whatsoever.
To that end, GameInformer has released no information pertaining to GTA 5 and has not provided us with any hints that it plans to do so. In the absence of these facts, the fans insist that "this will be the month" that GameInformer will allow GTA 5 to grace its cover—which seems to have become a monthly ritual for the crowd who want nothing more than to get their hands on the game.
Fans will continue to hope and yearn for more information about the upcoming Rockstar game, as information from the company itself remains relatively scarce.
Other potential covers include the new Metal Gear Solid, Watch Dogs, and Half-Life 3, but that'd be even less likely than GTA 5 at this point in time.
Expect the world to come to an abrupt and bloody end if the cover for November's GameInformer issue is Grand Theft Auto 5.
