The Windows 10 Version 1903 Media Creation Tool is now available:
https://software-download.microsoft.com/download/pr/MediaCreationTool1903.exe
The Landing Page for the Media Creation Tool hasn't been updated yet.

Despite the Tool Referencing:
- "MediaCreationTool1903"
- "File/Product Version 10.0.18362.1"
It does not give a:
- "Windows 10 Version 1903 Build 18362.1 ISO"
When I tested this tool I obtained a:
- " Windows 10 Version 1809 Version 2 ISO"
- "Created by Microsoft on the "12th of March 2019"
- The ISO is "Version 10.0.17763" and "ServicePack Build: 379"
