Google has published a video online of the event “Hey Google” Smart Home Summit, where one of the slides you can see the inscription “Checklist for September 8th 11 Android Launch”.
Also in this picture you can see the list of things that must be done to manufacturers of smart devices that support Google Assistant, before the release of Android 11.
Of course, this year make plans in advance is not necessary, and indeed Google had already endured the beta release of Android 11. However, last year release a stable version Android 10 was also held in early September. So on 8 September may be indicative date for us, ahead of the official announcement from Google.
