you have Phoenix's picture right now just incase people dont know what he looks like in GS4well Phoenix Wright is not in that game, but i heard he is like a mentor or something similar to Appolo...you know, its kindda like Mia + Mia old boss...
and there is a girl that look just like Maya (minus the training custome)....maybe she is Maya's daughter
but i hope the story is as good as Phoenix Wright....
He is in the game. It could probably be said that GS4's story revolves about him. I didn't read too in depth into the spoilers but that's my impression.
