last quarter of the trailer has some town scenery. the final shot is a large group of men riding horses together. that, along with the immediate mention of "online" in the original press release, the 7 men in the 2nd image of the game released, and the very public registering of "read dead online" makes me think this is going to be a multiplayer focused game. gta online makes a lot of money for rockstar and i'm sure they want to keep pulling those funds in with an additional game that has a lot of microtransactions

but the 7 men in the above mentioned image and trailer could just be a nod to the magificent seven. maybe RDR2 is going for a gta v style multi-character narrative with 7 people
