Sony will begin a concentrated publicity campaign for its Morpheus VR headset with a "four-hour" showcase at the Game Developers Conference in March.

Weeks ahead of its E3 media conference, Sony will send representatives to the Games Developers Conference in San Francisco to brief attendees on the prospects and challenges of developing virtual reality content for PlayStation 4.

Confirmed already is a one-hour speaker session, hosted on Wednesday March 4, entitled Beyond Immersion - Project Morpheus and PlayStation. Then on Thursday, a PlayStation US representative will discuss various insights into rendering for virtual reality. Sony has also booked seats on two public developer roundtables which will discuss VR.

But beyond this, games site Polygon claims that Sony will also host a standalone "four-hour event focusing on Morpheus." The showcase, set to take place on March 3, will apparently provide hands-on demos of the system.

For now, the session has not been listed on the official GDC schedule. GameSpot has contacted Sony for clarification.

At GDC in 2014, and after many months of rumors, Sony officially revealed Project Morpheus--a virtual reality headset that plugs into the PlayStation 4 and provides fully immersed gameplay akin to Oculus Rift.

Days after Sony's reveal, Facebook made the surprise announcement that it would buy Oculus VR--maker of the Oculus Rift headset--for $2 billion. Like Oculus Rift, the Project Morpheus headset is not yet available in a consumer version. Sony has ruled out a 2014 launch for the headset, and has promised that it won't sell for $1000.
