Leak suggests RDR2 will have 3 protagonists

A 4chan user known to leak information prior to game’s release has revealed Red Dead Redemption 2 is going to feature 3 main protagonists just like GTA V single player. Based on what he said,  Red Dead 2 is going to function almost the same way GTA V works.  Read Dead Online, the online portion that’s similar to Grand Theft Auto Online, except with horses will be coming out much later after the main game is released.
He also said Red Dead Redemption 2 will be a prequel and the 3 protagonists are members of John Marston’s old gang from the first game. However, the leaker says John is not in the game.
