As for me, the gameplay loop cemented that Kojima gets it.
Dont forget that we have confirmation that a lot of stuff was not shown on purpose in this demo, as confirmed by the publisher of the artbook. He confirmed there are different landscapes and region, teases stuff about how when port knot city is shown Sam goes straight to the delivery zone, but there is much more to see in the city, he teases the moon again.he's under nda but the way he teases stuff, he even says some stuff was stealthly shown in the demo but not pickep up on.
So in the end it really might be that this is yet another MGS2 trick, and the courrier in icelandic landscape is only a part of the game, maybe even just the beggining part. The publisher insist several times that there MUCH more to DS than what we already saw.
Edit : I'm watching the IGN video while waiting for the translated live presentation, and holy shit I did not notice that the chiral crystal are shaped like 2 hands !!!! Damn so that means that the giant BT in the trailer has some kind of giant living chiral crystal instead of a head.... so weird
Edit2: the description of the Ludens mask sunglasses :)
"An old favorite of Sam's. Sunglasses designed with "Homo Ludens" in mind.
Their form encourages the wearer to never forget their playful side". Mmmhhh interesting....
