Metal Gear Rising: Revengence teaser is rather confusing

I've gotta admit that I'm rather disappointed by this teaser for Metal Gear Rising: Revengeance. It looks as though Konami is planning some small webseries about the Raiden character, though for a series that has always reeked with style, this teaser video looks pretty mundane. Generic stock footage of nuclear bombs, crappily lit sets with some creepy looking b-actors skulking around… something tells me they didn't let Kojima get involved on this one. Otherwise the teaser would be at least half an hour long.

"You'll never be the same Jack" they claim. Wonder what that means? Raiden's real name is Jack, are they augmenting him even further, or will this webseries explore his origins?
