Actually no. He has shown that he does not blindly follow orders like Steve. I think he will ride the line between living up to the mantle and staying true to his past and trying to better the more overlooked aspects of the Marvel Universe. I think in general he may have a more liberal stance on many things and willing to "turn off the mic" when needed.
I do think Cage will be the one leaving, or She-Hulk depending on how the Gamma Wars arc in Hulk goes. I don't recall her ever having a big S on her chest in the past. For a minute I was trying to figure out if it was a new Sentry
The book should be good. It is already a great read, Land has done great on this title but Ross is a much less "fuse on dynamite" artist for fans.
Marvel is doing its thing with the Avengers line.
