Well the actual Silent Hill reboot is rumored to have Keiichiro Toyama helming the project, he was the director and original designer for the first Silent Hill game but left Konami afterwards and joined Sony so he can make the Siren horror series instead. Monster designer Masahiro Ito is suppose to be on the project, and its his coy twitter account that has this rumor stuff going crazy cause he stated a few years back that he would never work on another Silent Hill game unless he could kill off Pyramid Head, and then a few weeks ago he tweeted "RIP Pyramid Head". The final person supposedly working on the project would be Akira Yamaoka who did all the music. So if the rumor is true, the soft reboot entry (which isn't Silent Hills) would be developed by three of the core designers from the first entry.

As for Kojima Productions doing Silent Hills, I'm all for it cause Death Stranding was actually fantastic, and I'm sure the BTs were a left over concept from Silent Hills anyway. So I'm all for the project if it gets revived. I never played PT but I've watched enough LPs to know that I feel it was a step in the right direction.
