I'm experiencing an 'outside the box' moment. It wouldn't surprise me at all if Kojima intends this image to be shuffled around a bit.

Another possibility: interpret this equation literally ...

i + ! = (!)
i (as in 'I, Hideo Kojima') + NOT (! is a logic symbol) = In Power

Perhaps this is a sign that Hideo is handing over the reigns to someone else? (boo hiss!) In any case, I'm looking forward to seeing the outcome of this interesting teaser!

ADD: Try putting the 'power sign' on the top and use the cross as the body. Looks a tiny bit like the cyborg ninja, no?
