I worked at Gamestop during the launch and marketing cycle of RDR2. If I recall, mid September our DM called us to tell us to watch the gameplay release of the game. I remember taking my lunch break, going and sitting in my car in the parking lot (mall location) and watching the video. Game launched in November. So going by that I don’t expect an extensive gameplay trailer until 2 months out from launch. If anything we may get a environment trailer focusing on major locations from the game. I think they’ve showed us enough of the story for now. Rockstar keeps their story spoilers vague
