Even though there has been no official confirmation, Wright is almost a sure thing because at the end of season two, Dolores rebuilds Bernard from her memories after she escapes Westworld and takes up residence in Arnold's old house.
He told The Hollywood Reporter after the season two finale that he's "excited to explore" the idea of Bernard and Dolores as "guests" of the real world the way humans were "guests" in the park.
It is not far-fetched to think that Bernard and Dolores may actually be working against one another, as he does not have the stomach for violence and death the way she does.
