Its speculation, but probably reasonable speculation. At WWDC, I think almost every OS version gets an announcement of a major version bump. They will announce the next macOS major version, iOS major version, etc. So it is totally reasonable to suspect they will announce the next major version of visionOS. Edit: But since it is still so new, it could not be until WWDC 2025 that visionOS 2.0 gets announced.
