Microsoft’s put out XNA extensions for Zune HD, as you can see here.
The update adds the following functionality:
- The ability to target and develop for the Zune HD media player.
- The addition of new Touch APIs to the XNA Framework for use on the Zune HD.
- The addition of new Accelerometer APIs to the XNA Framework for use on the Zune HD.
Shit your pants right now, Apple. Actually, maybe hold off until Microsoft manages to release Zune anywhere else apart from America.
