I feel like the drugs people have to be hopped up on to seriously believe Microsoft is going to make investments in Japan and Japanese game devs should be so potent they'd prevent people from posting on the internet, but it seems like we've gotten quite a few of them today!
Microsoft BOUGHT a Sakaguchi owned studio and financed his games, and this was when Sakaguchi was a bigger name (in Japan) than Kojima. It failed. The Xbox One sold just a hair over 50k consoles in Japan. It's one of the worst console launches in ALL OF VIDEO GAMES. If you think Microsoft is going to just spend hundreds of millions of dollars to finance Kojima's games, build a studio for him, etc after all of that... You bought the wrong console and I'm terribly sorry.
