This new software was announced last week. I waited for more information and reactions before sharing it with you, but I haven't found any solid analysis or reviews so far. Esri announced the ArcGIS Pro beta program.
From the announcement: "Esri is pleased to announce the beta release of ArcGIS Pro, which is a new ArcGIS for Desktop application that provides many exciting features. ArcGIS Pro is designed for GIS professionals who need to visualize, edit, and perform analysis—in both 2D and 3D. All current ArcGIS for Desktop customers are invited to download ArcGIS Pro and participate in its beta program. Your work in ArcGIS Pro is organized into projects, which bring together all the resources you need to complete your GIS tasks. You can store as many maps and layouts as you need in the same project, and you can open multiple maps at once and view them side by side. You can package your projects to collaborate with others, or share your work as web maps and web layers. ArcGIS Pro can use local data, as well as content from your ArcGIS Online or Portal for ArcGIS organization. ArcGIS Pro is a 64-bit, multi-threaded application with a modern user experience that runs on the Windows platform."
