It has much more chances of being Sunny than Raiden's kid (and I think his kid looks more like Campbell... uh oh!). Mainly because of the hair style. But why is her hair gray anyway? That's weird. And the cyborg's hair is Raiden-blond.
BTW I have to ask again it the whole Famitsu interview somewhere, even with the XXXXX words? I need to read it all.
Right now, my bets are:
- Two games, one on PSP featuring Big Boss, a prequel. A sort of MPO sequel of sorts.
- One on PS3 (possibly 360 too), not part of the Metal Gear Solid line, but set after MGS4. This one is made by the MGS4 team. It has a similar feel to MGS.
- The cyborg is probably not Raiden or Sunny, but an out right robot/android, built by Sunny or Otacon. The only reason the eye is covered is because it has some sort of special use. The bandanna is Snake's (or in reminiscence of Snake), who might still be alive or not, who knows. The body or suit is made from Raiden's cyborg ninja body/suit, they don't have the resources to build something new from scratch. The game is basically going to be a way for Kojima to directly tie in a rebooted Snatcher story into the MGS world. Lucipher Alpha will probably turn out to be the mutated Foxdie from MGS4.
- It wouldn't be impossible that the Raiden at the end of MGS4 is not Raiden, but a "Snatcher" replacement, while the real Raiden is still a cyborg ninja, for some reason. But I doubt it.
