I don't think there is an implication that these characters will be any way like the earlier characters, rather that those characters were sort of archetypes of humour. You've got the guy who acts tough but is really a chicken, and you've got the guy who is rough around the edges who is a reflection of the "common people". I expect a lot of great comic relief from Danny McBride, and in some ways I hope they don't take his comedy too far.
