The latest build of Mac OS X 10.6.8 has been seeded to developers. This build lists no known issues, and it has the exact same focus areas as an earlier build: AirPort, Networking, Graphics Drivers, the Mac App Store, QuickTime, and VPN.
There's no indication of when 10.6.8 will see public release, but with OS X Lion due next month, it's likely it will be one of the last major updates to Snow Leopard.
