Here's the list from the article:
1. Tweaked UI
2. Near Field Communications (NFC)
3. New Motion Control APIs
4. Native Video Chat
5. New Android Market
6. Google Music
7. Support For More Large Screen Devices
8. Virtual Keyboard Enhancements
9. Support for WebM and VP8
10. New YouTube With Broadcasting
11. Google Me or Social Gaming Network
12. Flagship Phone – Nexus S

This list is comprehensive given the information released so far, and if true, would make a wonderful release.

I like the fact that Android is incremental. Each update makes the OS better, without going back to the drawing board. It seems that features are very well thought out prior to implementation.
