There are no preset release dates for any of the beta endpoints, they are released only when Microsoft deems them ready for GA. It can take weeks, months, or in some cases even years. Best you can do is keep an eye on the Graph changelog (you can subscribe to RSS): https://developer.microsoft.com/en-us/graph/changelog/
