First screen on Multiplayer:
Multiplayer info will be spilled the week of the 5th of April.
I notice the little "-" next to names. Maybe it's just to let you find gamertags faster but I think it could show you a persons moral standing. "-" meaning neutral, and upwards arrow for good and a downwards arrow for bad. Just my speculation.
Edit: The image above is called "rdr_multiplayerweek_announce" so maybe the MP info is a week long thing. If it is, I hope it ends with a video of MP in acton.
