It wouldnt matter.The group of people that would buy the PSVR, would buy it even if NX came the same day as PSVR, and the people that are not interested enough in it is not going to use its extra money just because NX was delayed 3 months.
People forget that PSVR is too expensive and too unproven to have that kind of mass appeal that consoles or handhelds(or cellphones for that matter) have.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
