Frank could just be his best soldier, or protege. While ocelot is the second on command after he falls out with Kaz. I just hope to lord Kojima that franks origin is retconned to ignore the atrocity that was PortableOps
I have hopes for some good retcons out of this game. For one thing, Big Boss needs to be evil, and not the misunderstood hero that he was at the end of MGS 4.
But, I didn't really mind the "Null" thing, to tell you the truth (as corny as it was) . I just found it strange that Fox wasn't in Peace Walker at all - considering that he was rescued by Big Boss. They should have held off his appearance for another game, instead of introducing him like that in Portable Ops. But, since Portable Ops was meant to tie-in with MGS 4 - I don't think KojiPro anticipated that the series would continue for this long.
