Something I wish that was really elaborated upon with in the manga. We know why the Gold & Silver bros were in possession of their sage weapons, for power, but that isn't what Itachi is about, his character isn't power hungry or driven. What made Itachi search for these God tier weapons? and for what benefit? Could it be that he was aware that Orochimaru had his eyes on them, and decided to pursuit action by removing them from dangerous hands? Was it a contingency placed for Alatsuki? or were they something he just came upon by dumb luck?
