Maybe this'll finally be his chance to break away from being pigeonholed and do something original for the first time in 14 years (ok, ok. He did do Silent Hills
)
I imagine that him leaving Konami after MGSV means that he wont really get time to do anything with it. But yeah, I'm with you, I really hope he gets to work on some more adventure games and other smaller projects for him to play around with. I love MGS more than anything but it's a huge unwieldy mess of lore and characters, so seeing him work on something small and new would be awesome
