Steve Haynes from Esri has published an update about ArcGIS Earth on their company blog.

ArcGIS Earth is an interactive 3D experience for users to plan, visualize, and evaluate events on the globe. ArcGIS Earth provides situational awareness of an environment on desktop and mobile for improved decision-making. Ingest data in different formats, including 3D models, KML, TXT, and open services from ArcGIS or with a URL, to explore areas of interest in 3D. Manipulate KML in its entirety to understand changing circumstances. ArcGIS Earth is a free and easy-to-use tool to quickly fuse, manipulate, and collaborate with 3D data for research, planning, supporting time sensitive briefings, and graphic presentation.

The ArcGIS Earth October 2020 release includes new 3D capabilities, support for additional data types, and many user experience enhancements. With the October 2020 release of ArcGIS Earth we have migrated from the .NET Framework to .NET Core.
