Good, looks like he won't be wasting years to build a new engine... for now.

Hideo Kojima has confirmed that his first post-Konami game will use a third-party engine, and that his well-documented trips to meet creatives - in video games and otherwise - have at least in part been to find which tools his new project will utilise.
Speaking at the Nordic Game 2016 festival, Kojima explained that in order to ensure a timely release for the new Kojima Productions' debut, he had to go against his preferred methods:
"I actually think it's better to make games using internal tools," Kojima said. "As for my first title, because I want to release it to the people who are waiting for it, for that title we are going to use a third-party engine - the reason I am travelling around the world is looking for such technology to use."
