The source came from a former Rockstar employee's site so I doubt it being fake but what it exactly is, well that's the question. lol
Said Rockstar employee hasn't been with the company in nearly a year so the screenshot is pretty old and his previous work in Red Dead Redemption was working on building structures and towns.
Why do people think it's going to be called Red Dead Redemption 2, wouldn't it be the third game in the series?
My bet is on Red Dead Retribution.
Red Dead Redemption was more of spiritual successor than a direct sequel to Red Dead Revolver, so Red Dead Redemption by itself became this new franchise but it's still the "Red Dead" brand. People just speculate the RDR2 title because from the leaks including the possible map it looks the next game takes place in the East for more of a Dakota/Louisiana landscapes with some areas from RDR present and available to go to including West Elizabeth.
GTA V was released in 2013. and since then they released PS4/X1 and PC versions. So 2017. will be 4 years since new game from R*. Also as far as i know R* North and R* San Diego work on separate projects. I don't know how long is R* San Diego game in full production but i am 99% sure that they were working on next game at some capacity since Fall 2010 or Early 2011. That is enough time for game to be released in 2017.
RDR Remastered could be done by support studios like R* Leeds and R* Toronto.
Oh yeah I believe the new Red Dead will drop May 2017 but didn't the Take Two earnings call from a couple weeks ago already lay out what was being released this fiscal year? Nothing from Rockstar was mentioned I believe.
Also doesn't Microsoft actually have to get permission from the developer before they even begin testing or working on BC? That's why when RDR BC got "leaked" makes it sound fishy...like I'm still expecting a new Red Dead to be announced at MS conference and as a preorder bonus they're going to throw in the RDR BC that day.
