I listened to English podcast:
http://www.konami.jp/kojima_pro/radio/the_report/the_report_152.mp3
here is a summary
gameplay is 100% Platinum Games, Story and cutscenes done by Kojima Productions. They go and check out with other, making sure characters and world are presented correctly in the game as it should be in Metal Gear universe.
they talk a lot about game's development, you should listen if you're interested.
They want to go all out with action, crazy scenes that you haven't seen in the series from Kojipro before.
The old MGS Rising story was set between 2 and 4, but when they decided to go to platinum they decided that it was limiting and changed it to set after MGS4. PG's game design demanded the story to be changed, gameplay comes first etc. They think it was a good decision.
About Zan-Datsu:
It was a a concept revealed in E3 2010, it's now taken away, they think it slows you down, you still cut thing as you see but it's different than the concept shown in E3 2010. "Gameplay comes first" again.
Who's the director?
When talking about director at PG, Kamiya is the first name to come up but he's not directing, they are unable to reveal it yet but they have great talent there for action games, it's a great team there etc.
This time the whole work flow is toward English, they will be releasing English trailers first, game is directed more to western audiences, they try to develop with that in mind. Even if game design can not be released in Japan that's fine, western gamers come first. Talking about shooters etc and how it's the biggest market. They are aiming for a global market.
This doesn't mean they are copying western games, they are making what they want, it's still a Japanese made game, but they had that in mind. They are making games, games that are fun, but thinking who will find it fun.
