Well, considering the first Red Dead was console-only (though far less popular), I don't know how you could make the assumption that the sequel was coming to PC. GTA, on the other hand, has both its roots in PC and an established routine of the major titles being ported with superior features 6-8 months later. I don't blame you for being cynical, and it would be a major disappointment if it fell through, but there's no reason to think that won't be the case this time, as well.
