I would bet the entire One Piece that it is not Shanks. Yeah Luffy is happy, he already has intent to kick the crap out of Big Mom and is so excited that he has got someone else interested in help make that happen sooner rather than later. If it were Shanks they were going after I think Luffy would hate the idea and probably wouldn't think he is ready to show Shanks he has become the great pirate Shanks requested.
