BTW does anyone else think the S in "Hills" is a 5? Because that is both stupid and reasonable, which is very Kojima.
I... would not describe Kojima the same way you do. If anything he has shown over the years to be incredibly perfectionist at what he does. But anyway, to your question; All the little info I've read is that Silent Hills along with any ending you might get is gonna be procedurally generated, and because of this the name refers to the different kinds of Silent Hills players will experience individually.
I don't know the source of where that "info" came from, but the procedurally generated part sounds way too exaggerated for me to believe it. Either way, what really matters here is that after 10 years a brand new Silent Hill is finally back in good hands.
And like I said in the misc. gaming news thread, I hope this is a reboot. If it has
to be part of the main series things could get more than messy with the state of the canonicity of the series. SH Origins to Downpour are part of the "bizarro timeline" since most of what happens in those games doesn't make that much sense overall with what was shown in SH1-4.
Still, I have faith in the project.
