Sony is preparing the ground for a March 15 press event to do with its PlayStation 4 virtual reality headset, PlayStation VR. The PlayStation VR kit is still without a precise price and release date, while fellow 2016 launches Oculus Rift and HTC Vive have already staked out their ground.

PlayStation CEO Andrew House has been quoted as saying, in a September 2015 interview, that the PSVR will be “priced as a new gaming platform.”

For many, that translates to a $399 launch price, the same as the PlayStation 4, but it could be more. The PlayStation 3 was introduced in two configurations at $499 and $599.

The Oculus Rift’s consumer version is being introduced at $599 with a first batch to be shipped from March 28, while the HTC Vive VR System, which packs in two base stations and two motion controllers, has marked out a $799 launch price for April; pre-orders for that are to start two weeks before PlayStation’s VR event, on February 29.

Sony’s PlayStation VR announcement takes place during the Game Developers Conference in San Francisco, which runs March 14-18.
