The first game was called Red Dead Revolver, then Red Dead Redemption, so if a new one comes, it will be Red Dead ___________. Assuming it starts with a R to continue the alliteration, but not Redemption 2. The only way I can see them continuing the Redemption story is if you got to play as John Marston when he was in the gang before he got shot and left to die. Otherwise, the story is pretty much fully laid out in the game, some say Jack's story afterwards would be interesting, but he was just a brat to me. Not a memorable character at all, much less interested if an entire game revolved around him. Rockstar has started from scratch both times, Revolver and Redemption have nothing in common besides the old west era, so I'm assuming the trend would continue. I would love to see the next game be announced at E3, just bugs me when people assume it'll be RDR2, especially when it's just a rumor to begin with.
