I don't really care to be honest with you there have been so many bad Silent Hill games it sounds stupid to bitch about something like the perspective as if the other Silent Hill games that released in the past had no problems because you could see someone's back or something.
So to be honest with you if its in 3rd person by don't really care if it's in first person I don't really care the main concept to silent Hill has very little to do with perspective as we're not talking about Call of Duty and we are not talking about DMC in which the perspective of the game matters to some gameplay concept.
If Kojima's team indeed is working on silent Hill it's a day one regardless of perspective
