Got my PSVR on Thursday, too. It's a lot of fun (although I sometimes have trouble adjusting it after putting it on ^^'), but I'm still a little sceptical concerning RE7. All VR titles I know so far are quite short, so I wonder how long it will take to finish RE7.
And seeing how much you already immerse into a game like Until Dawn: Rush of Blood, RE7 might be really really frightening in VR.
About the Kitchen-demo... is there a way to stand up from the chair and move around? (Didn't watch the vid, sorry ^^')
