From another interview:

I'm very interested in that stuff whether it be the facial expression readings or something also. But we're having a hard time with that and we're not sure if we'll be able to implement something for MGSV. But we're still looking at it and are really interested in the new Kinect.

Kojima certainly knows how to use hardware in surprising ways. Reading the radio frequency off the game case, plugging the controller into the second port, commenting on the games you've played by reading your memory card, loading a week old save and having the boss you're fighting die of old age...

It's statements like these that actually make me want Kinect.

Playstation getting the superior version confirmed!

Epic. Didn't know about that one.

so pumped for this game. was shocked it was on Xbone but at least my bro can play it again. he was a huge fan of MGS,2&3 but skipped 4 purely because of its exclusivity.

How could you seriously not know about that one? It's probably one of the best (and most well-known) secret in the MGS universe. Just like the one in MGS1 on which if you had the audio settings on "mono", at the Hind-D battle the Coronel critisize Snake for not owning a stereo TV (Because sound is very important in that battle).

Good to see him expanding :) although..... it's weird seeing this

Oh dayum, didn't know that either!

I'm a pretty shitty MGS fan huh?

You didn't pay too much attention to details =P

Here, check this.
