Last call to pre-order a PlayStation VR - today, June 30, starting at 7 am Pacific time both the VR Launch Bundle and VR core will be available. Supplies are limited and there will be no more pre-orders until the October launch.
You can place your pre-order on GameStop.com. The PlayStation VR core costs $400 and includes the VR headset, stereo headphones and a VR demo disc.
The PlayStation VR Launch bundle costs $500 and adds necessary hardware you may not have - a PS Camera, two PS Move controllers and a PS VR Worlds disc. If you bought the PS Move back in the day then you already have the camera and controllers so you can go for the cheaper bundle.
Sony previously did a quick pre-order in late March. Sony is targeting 6 million headsets sold for this year, an ambitious goal (especially considering that the launch is late in the year).
