I can see horses included in this easily. Imagine a chase mission with Trevor riding through the scrub on horseback trying to ditch the cops hot on his tail.
We now have many animals in V so with the established horse mechanics from RDR I really can't see them not being included.
I think they will keep horses for a Red Dead sequel.
All they need to do is bring back the Unicorn and I will be satisfied. --- GT: TheAnalogKid06 Can't wait to play: Last of Us, Watch Dogs, GTA V, Killer is Dead, Dark Souls 2, A Link to the Past 2, MGS V, Amnesia: A Machine for Pigs.
