The only bit of information that is important in that video is the revelation that he hasn't even settled on a game engine for this game yet. We should start taking bets on how many years away this game is from being released, I reckon 2020 at the earliest, though seeing as he will be using someone elses game engine instead of making his own I suppose it could speed things up, so 2019 might be a possibility, but nah, being Kojima I reckon he'd like the symbolism of releasing a game in the year 2020, don't know why, just reckon he would.
