Another point that adds to the likeliness of Kojima partnering with Microsoft for his next game is his studio’s announcement confirming the development of a new project.
Kojima Productions’ twitter page had also announced that they were looking for best-in-class talent to join them. The tweet was made in October 2020 and said that the hired people would work out of Kojima Productions’ Tokyo studio.
The studio’s career page shows they are looking for programmers, artists, writers, and other professionals to work on game and sound design.
