Forum:Anderson in ME3

Something I am curious about. In everything being shown about ME3, you see Anderson as an Admiral as he helps you along in the beginning. The Voice Cast video listed Keith David as playing "Admiral Anderson". But as my Paragon Shepard always chooses Anderson the join the Council, I pose these questions. Wouldn't that(or shouldn't that) have any, if not bigger, impact on the game over him being just an Admiral? Also, would he(or should he) even really be present during the opening of the game? I would assume the other Council members would call to have him stay on the Citadel. I am just wondering how that may change the game dynamic.
