Ok Ok. After some digging. I think we already had norse clues in GOW games.
Look what I found in God Of War Ascension:
http://godofwar.wikia.com/wiki/Mjölnir
Yep that is
Mjölnir; Thor's hammer. I don't think this is innocent or pure hazard.
In fact ascension had a hidden secret mentioned in Neogaf before:

Look at the second mural pic: Kratos is still alive after the second great war is over.
The third mural is the most interesting one:
In greek mythology and GOW there are some analogies between greek and norse lore:
this example of analogy is very interesting since it may be the connection between both worlds if it is the place were all the pure souls from the universe go to:

Kratos fighting with the norse has already been applied in this non official de-make called Bit Of War:

From Kratos wiki page:
http://godofwar.wikia.com/wiki/Kratos
And from God Of War III wiki page :
http://godofwar.wikia.com/wiki/God_of_War_III
You see? The idea has been planned for long time now, or let's say
from the beginning and it has been plotted by the directors of all epiosdes. That is why I am sure that Cory Barlog knows very well what he is doing now.
Gooing back to what shinobi602 said:

What I highlited above and what shinobi602 sparkled is making me confidently assert what I said before:
http://www.neogaf.com/forum/showpost.php?p=200224402&postcount=1449
What I fear from shinobi602 post is that we may face another MGS2/DMC4 syndrome where devs wanted to try forcing a new character to the series helped by the series main protagonist with whom we play only for a short time while the rest of the game is being played by the new rookie. This will result in being nostalgic about the previous hero and just waiting for the moment to control him even if it is short or late in the game.
I just hope I nailed it and uncovered most of what is being cooked for this game. Also Egyptian mythology incoming (in this episode or in a newer one).
