Gurman also reported that Apple’s glasses would overlay information such as text messages and maps in front of the wearer’s eyes and that users will be able to control the glasses with Siri.

There will reportedly be an AR or VR headset announced sometime in 2021 so it would appear that the headset will be released before the glasses.
