Solaris 10 10/09 is now available for download but it is yet to be announced and have all download links updated.
Anyway, here is a working link. New documentation is also available on docs.sun.com, including the What's New in the Solaris 10 10/09 Release.
The changes are pretty much in line with my earlier predictions.
Update: Joerg Moellenkamp has nice summary of what's new.
