PlayStation VR will be fully compatible with PlayStation 5, the next gen that should be available on the last months of 2020. The device has sold more than 5 million of units and the future compatibility with PS5 will help to sell even more PS VR.
Immersive VR Education released a financial report in which they have dated PlayStation VR 2 for this year. Here it is:
“In 2020, Sony will release PlayStation 5 and a new version of the PlayStation VR headset (PSVR), which will further expand the high-end VR user base – the group intends to support this device with its current software package.”
I think is too ambitious for Sony to release to piece of hardware for one period, but who knows.
