This is exciting news. Microsoft just announced Project xCloud, a streaming service similar to GeForce Now or Onlive (when it was up), but with the capability to play on any* device.
This video tells you everything you need to know. For more see the article on Project xCloud at the Microsoft Blog.
Microsoft has been going strong lately with the announcements. Just last week we found out that Android phone users will be able to mirror their phone and apps on their Windows 10 PC. This is coming soon whenever the October Windows update is released.
*I’m guessing “any” means a newer generation phone or tablet over wifi. The video mentions 5G readiness so someday that will be an option too. Can I play Forza Horizon 4 on a PS4?
