Mark Gurman, in his Power On column for Bloomberg:

Apple is now working on a major effort to support third-party hand controllers in the device’s visionOS software and has teamed up with Sony Group Corp. to make it happen. Apple approached Sony earlier this year, and the duo agreed to work together on launching support for the PlayStation VR2’s hand controllers on the Vision Pro. Inside Sony, the work has been a monthslong undertaking, I’m told. And Apple has discussed the plan with third-party developers, asking them if they’d integrate support into their games. [...]

One hiccup is that Sony doesn’t currently sell its VR hand controllers as a standalone accessory. The company would need to decouple the equipment from its own headset and kick off operations to produce and ship the accessory on its own. As part of the arrangement, Sony would sell the controllers at Apple’s online and retail stores, which already offer PS5 versions.
