People need to stop with this stuff... Seriously.
Team Silent has been disbanded for years... Konami has been mismanaging their franchises for years. Kojima tried something with P.T, but the whole thing felt apart and now Konami is so salty they can't even allow people to download the demo they have on their accounts or play it on PS5... Why would they suddently decide to give away their IPs ?
There's already strong evidence that Kojima is working on a new horror game. It'll probably end up being really close to what P.T was, with people like Guillermo Del Toro, Norman Reedus and Jinjo Ito being involved like they would have been on P.T anyway. Does it really have to take place in the foggy town of Silent Hill ? P.T was about ghosts anyway , not big bloated flesh monsters like in Silent Hill, it didn't have a town, no fog, and it was a great horror teaser.
So yeah, just like MGS and Castlevania, I think it's best to move on and accept those two franchises are pretty much past their prime, and play the new generation of games (like bloodstained) instead of asking for Konami to "do the right thing" and not mishandle their franchises into other trashy Pachinko machines.
