I'm not sure exactly the direction this is supposed to take the story, but Konami has announced some new DLC for Metal Gear Rising Revengence that adds some VR missions as well as a new sword ([link]). I think this was supposed to tie up the confusion of what happens to Snake but who know? Either way, I might actually consider checking out this DLC, if only for some more Kojima Brand hijinks he's so well known for.
