That leaked map doesnt have a train line but there is a train present in the trailer.
Wot!? It says "railrod" and goes all over the leaked map. I mean everything is quite accurate to the leaked map, so if the leaked map was fake then Rockstar trying to make the leaked map look real in this trailer. That I find unlikely.
In the FAKE leaked map and the cleaned up FAKE map the rail roads don't connect. Sure they could be separate due to mountains but they also made tunnels back then so that's another reason why I think it's not the real map. They should connect so people and goods can get from town to town.
Too bad Mexico isn't in. Liked the diversity of the first RDR. So based on all your findings the leaked map is indeed real. And all footage was from the heartland(s)?
Don't be so quick to judgement. We haven't seen everything yet. I believe Mexico will be bigger and better than RDR1.
