During a business briefing, Sony revealed that PlayStation VR 2 will have over 20 "major" titles at launch. The presentation didn't specify the names, but we know that Horizon Call of the Mountain will be one of them. Others will consist of first- and third-party titles.
“Right now, there is a considerable amount of money being spent on partnerships with independent and other third-party developers to secure a considerable pipeline of attractive VR content at the launch of PlayStation VR2,” said SIE president Jim Ryan, in a comment reported by Video Games Chronicle.
Aside from Horizon, reports state that PS VR2 will have some games from Coatsink (known for Jurassic World: Aftermath), Fast Travel Games (Wrath: The Oblivion), First Contact Entertainment (Firewall: Zero Hour), and nDreams (Phantom Covert Ops).
PS VR2 will have an OLED display offering 2000×2040 resolution per eye and frame rates of 90/120hz, as well as 3.6X faster GPU frametime with foveated rendering and eye tracking.
