There are currently "about 100 or more" PlayStation VR games in development, Sony CEO Kaz Hirai told the BBC.

The PlayStation 4's virtual reality headset doesn't have a firm release date (or price) quite yet — it's said to be launching sometime this year — but at CES 2016, Hirai confirmed that there are at least 200 developers currently at work on games for the platform.

These include Double Fine with Psychonauts in the Rhombus of Ruin and Testuya Mizuguchi, who's working on Rez Infinite; both games were first seen at PlayStation Experience 2015 in December. The sequel to cult favorite Rez will be playable on both PS4 and the VR, while the Psychonauts spinoff is a VR-exclusive.

Formerly known as Project Morpheus, the name change came in September just before Tokyo Game Show 2015. Sony talked a bit about VR system during its CES address this week, which prompted BBC's questions about its futures to Hirai.

"For us, it's all about making a better and more immersive gameplay experience, which separates us from everyone else," Hirai explained, referring to competitors Oculus Rift and HTC Vive Pre, both of which are on display at CES this week. The Rift and the Vive Pre will be available this spring.

Correction: There are, in fact, demos of the PlayStation VR available at CES this week. The text above has been corrected.
