Soon there will be another way to pre-order Sony's PlayStation VR.

A $499 Launch bundle is on sale now, but units are going quickly. So Sony will start accepting pre-orders for a $399 "Core" bundle at 10 a.m. ET on March 29, which comes with a PlayStation VR headset, cables, stereo headphones, and a VR demo disc.

The Launch bundle adds a PS Camera, two Move motion controllers, and a PS VR Worlds disc. Sony cautioned last week that it will be available in "limited quantities," though it plans to offer more Launch bundles this summer.

When the PlayStation VR formally arrives in October, it will be met with several competitors, including the wildly anticipated Oculus Rift, as well as HTC's Vive and others. Sony believes it has the upper-hand, thanks to its PlayStation 4 integration. At this point, however, the VR market is anyone's game.
