Next season, as it stands now, might not carry the show as well. No more Jimmi, no more Anthony, Jeffery's character being some conflicted soul sounds super boring. If Ed Harris is in next season (im sure he will be, by the grazing wound he took) hes not very interesting as a sympathetic character (ie - i want to help you be free!)
My hope would be that theres a great deal more twists, maybe Bernard and William start out helping the sentient robots but decide they have only the most cruel aspects of humanity in them (from Ford) and aren't worth it. so they have to save the remaining humans and try to get Maeve, Delores, Bernard, and some ensemble of remaining humans out before everything collapses. Throw in a twist were Ford isn't really dead or some kind of robot clone commander and it could be pretty elite.
