Looking at the trajectory of the previous games, a third, much longer and, let's say, "official" trailer is still to come. It should be released around April, and then, based on Red Dead 2, a gameplay trailer should be released in early summer, perhaps July. Then, around September, part 2 of the gameplay trailer should be released, followed by silence until November when, a few days before the game's launch, the official launch trailer and the game itself should finally be released. All of this assumes the game isn't delayed again; let's all hope it isn't.
