Has nothing to do with it but you could buy 2x Star Wars PS4 bundles for this price in the UK they are £249 each or 2x Gears of War bundles + Halo 5 for £499 as they are £238 per bundle + £34 Halo 5 as a context.
If Sony could hit that $350 PSVR price mark which going by console prices could mean a £249- £299 that would mean you could grab a Star Wars PS4 bundle + PSVR for £499 and works out of the box with the PS4 hardware which is the same as this headset which also requires a Graphics card at £450+ as a minimum without even thinking about the rest your rig.
Maybe PSVR is also going to cost a lot more than most people though as well so not sure.
