Danny Ross has a history of working at various locations and getting fired from them. He was a former intern and staff member at The Opie and Anthony Show (Sirius XM radio show), the former Executive Producer of the Lazlow Show, and a former employee at Rockstar Games.
Ross had a good relationship with Rockstar. Before working for the developer he attended Multiplayer Events held by Rockstar themselves as a part of the Lazlow show. The professional bridge burner took to Reddit to answer some questions regarding the Opie and Anthony Show, Lazlow and Rockstar.
In a response to a fan's question regarding what Rockstar had planned for the future, Ross made the comment: "Really? Dumbass. Really? Two." This response was translated by Redditors as Ross' way of saying 'RDR Two' — you know, Red Dead Redemption Two.
It's hard to say whether or not his 'hint' has any credence to it. He could be a troll or upset with Rockstar for some reason or another. Rockstar has not confirmed anything about a Red Dead Redemption sequel, but they have said that they are working on both new games and "offerings" from established franchises.
