The price of PlayStation VR, the virtual reality system built for Sony’s PlayStation 4, apparently leaked when Forbes spotted an early listing for the device on Amazon.

The listing was promptly removed on Thursday and Sony issued a statement — “This was an error by Amazon, we haven’t announced the price for PlayStation VR,” the company said.

But if this listing was accurate, Sony’s PlayStation VR will cost $800. That would mean the virtual reality system, which requires a PlayStation 4 to operate, will actually cost roughly double the price of the PlayStation 4 itself, which retails for about $400.

We’ve reached out to Sony and Amazon and are waiting to hear back.

This news comes just days after we learned the price of another major virtual reality headset that’s going on sale this year: the Oculus Rift, built by Facebook-owned Oculus VR, will cost $600 when it begins shipping in late March. (Though it's important to note that system also requires a high-end gaming PC in order to work.)

For many people, this is all too expensive. But if you're dead-set on buying a first-generation virtual reality system, keep this in mind: the Oculus Rift with an Oculus-certified PC will cost around $1,500, whereas buying a PlayStation 4 with PlayStation VR will only cost about $1,200. In that sense, it's cheaper to buy into Sony's virtual reality system, even though the VR equipment is so much more expensive than the console it needs to work.

Aside from Oculus Rift and PlayStation VR, we’re still waiting to hear about a price for the HTC Vive Pre, a promising virtual reality system borne out of a partnership between HTC and the extremely popular gaming company Valve.

But if the price of Playstation VR is any indication, it looks like all three VR offerings from Sony, Facebook and HTC/Valve will be rather expensive, at least to start.

PlayStation VR is expected to launch in the first half of 2016.
