Coming Soon = Spring of 2006!
I was under the assumption that this information can not be made public, but it looks like it has been by Loren at Search Engine Journal.
1. Improvements in Relevance : The ads that are shown by YPN are based upon what Yahoo calls its ‘matching expert’s. These ‘experts’ will be expanded to include :
* Contextual Engine : Targeting based upon the content of the page
* Ad Targeting : Publishers can “tag” their own site by defining their ad targeting category in the YPN admin
* User Data : Behavioral targeting or profiling (geographic & demographic)
2. Wire Service : Offering publishers payment via direct deposit this Spring
3. Expanding Invitations : Continuing on reviewing and approving thousands of high quality web publishers
4. International Rollout : Global expansion beyond the United States to English and non-English speaking countries
5. Yahoo Search Box : Publishers can add Yahoo Search to their site which will pay publishers a percentage of sponsored search revenue
6. Integration into Yahoo Answers : Yahoo may be offering its registered users the ability to earn revenue or points for contributing to Yahoo Answers and other user generated content offerings.
I think these much anticipated updates will be very well received. 
I think most of us knew this was on its way in some form. The question is when? Coming soon is not real specific
Sorry, I just clicked on the link and saw that it says “Spring”. I would have thought it would be within the month but I guess they are taking their time.
