Ah, missed this line at the end of the description:
Psychonauts in the Rhombus of Ruin is coming exclusively to PlayStation VR this year, and will chronicle the events between the first Psychonauts and the forthcoming Psychonauts 2, which was successfully crowdfunded earlier this year, and headed to consoles and PCs in 2018.
Oh, fucking hell. Good. I'm happy Sony moneyhatted something like this, but if a kickstarted Psychonauts 2 became a VR title, I'd have blown a gasket. My other thought that it would be a VR-capable first-person game, a thought which also left me cold.
