With Kojima's split from Konami being pretty ugly, fans have given up hope that he will ever get the chance to work on Silent Hill. However, a new rumor claims that Kojima is in talks with Konami to do just that, and is in talks to work on a new Silent Hill game. This rumor comes from Reddit poster Sarkzt0001, who apparently provided evidence to Silent Hill subreddit moderator MarcellusDrum to back up his claims. The evidence provided doesn't confirm Sarkzt0001's claims with 100% certainty, but it was enough to keep the post on the subreddit. Needless to say, fans should take it all with a grain of salt before they get too excited.
According to the leaker, the collaboration between Kojima Productions and Konami on this new Silent Hill game is the reason why Ken-Ichiro Imaizumi recently left the studio. The leaker claims that Imaizumi "went against" the collaboration with Konami, as he didn't want to work with Konami again. However, Kojima reportedly wants to finish his vision of Silent Hills, as he thinks "his fans deserve it."
