Microsoft rumored to be working on its VR headset

Sony is rumored to unveil its own virtual reality (VR) device at GDC over the next couple of days, but now its next-gen console competitor, Microsoft, is also rumored to be working on its own VR headset.

The Wall Street Journal is reporting from its sources that "people familiar with the project" confirmed that Microsoft is developing a VR headset, and that the company has already filed a patent for the device. The technology has reportedly been developed side-by-side with another project called "Fortaleza," something that translates to "fortress" in Portuguese.

The two projects are expected to provide users with a "suite of experiences unique to Microsoft's Xbox products."
