I saw nothing in the located spot but on the middle island it looks like something is jumping up it.

It did look like some white thing came up just as the screen went black. No way to explain surviving that much blood loss except "Yea, that pale bastard's immortal".

I watched that video in 720p on my LEDHDTV hooked to a computer. All I could see is Kanye West having sex with a gay fish.

They should replace him with Raiden:

If he can take Snake's place why not Kratos'

Pale skin.  Runs around naked except that you can't see his balls.  Crazy body tatoos.  Fights/Kills his father.  I think you're on to something!!

its nothing... if you look at the big mountain near the middle of the screen and you look slightly down to the right you'll see a spirit-(idk exactly what it is) float up, witch i think is what your seeing on the blue island except the video cuts of and you cant see it fully float up

Just before the screen goes black I see something white in that area.

Looked at it again on my PS3 this time

It really looks like someone is walking xDD. And the music really sends goosbumps through my spine because of the perfect timing. I REFUSE TO BELIEVE ITS NOT KRATOS :D

Don't yo mean swimming?

It's obviously Kratos's brother.
