Microsoft provides a Microsoft 365 Roadmap site that lists out upcoming features and provides proposed dates for release. The site also provides a filter mechanism, allowing you to display only the products you’re most interested in seeing. Intune is included as a filter so you can identify upcoming features.
Filtered just by Intune: https://www.microsoft.com/en-us/microsoft-365/roadmap?rtc=3&filters=Microsoft%20Intune
Additionally, you can apply more filters to pare the list down to in development, rolling out, and launched.
