In an interview with the Official PlayStation Podcast, Hideaki Nishino, SVP of Platform Experience, said the PSVR games will not work with PSVR2.
At the 29th minute of the conversation posted today, Nishino shared the following statements about the PSVR2:
“PSVR games are not compatible with PSVR2 because PSVR2 is designed to deliver a truly next-generation VR experience.”
“PSVR2 has much more advanced features, like [an] all-new controller with haptic feedback and adaptive triggers, inside-out tracking, eye tracking, 3D audio is coming together and 4K HDR, of course. This means developing games for PSVR2 requires a whole different approach than the original PSVR.”
With the absence of backward compatibility, the PSVR2 won’t be able to play over 660 PSVR titles released since October 2016 (archive).
The new headset may not be as desirable to buy due to its more limited game catalog. However, Sony has stated there will be over 20 major games at launch.
