The only one who would really be out of place in that pic is Togusa. As far as I know, Saito was "recruited" before Kusinagi joined Section 9. I cant read or speak Japanese so I assume the "2027" flash in the trailer is the year this takes place in(S.A.C. is 2030). That would cause a continuity issue as Togusa was (again, as far as I know) recruited into Section 9 just before S.A.C. began.
