The Vision Pro was a Development Kit; Just like the first generation Apple Watch. It's not meant for the consumers, it's meant for the developers among the consumers.

We will see if they ever release a new VisionOS device, but it's not the first time they did that; see also the Apple Watch.

You can explain away every failed product launch with "it's a developer product", not meant for consumers.

This wasn't like HoloLens or Google Glass. They marketed these devices to consumers and then sold these devices to consumers.
