I know this question has been asked before, but what do u think/want this sequel will be about? Personally, I don't want it to be about Jack after he killed Ross, I want something new. However, I would tolerate a prequel to John Marston's early life and gang days OR a game in between John's abandonement of the gang and the beginning of John's mission for redemption. I beleive the first one would be more of a success. The second one might be good for a DLC, but it might bore many players out because it would probably focus more on ranching and farming missions.
Anyway, i'm quite excited for this news. Although I think a sequel might take a long time to come out (I estimate 2016-2017) i'm looking forward to indulge into more RDR, not to mention that a new release would really start up more action on this wiki.
