Apparently the updated binaries from the last release were just an update/fix for CU6's RGS problem. What I originally called CU7 was actually something along the lines of CU6a.
This time around though, is the real Cumulative Update 7.

There are many Lync-specific fixes so if you are planning on deploying Lync and will have a coexistence period, I would install these on your OCS 2007 R2 server setup before installing Lync. This is only a personal opinion but it looks like it would avoid some known gotchas.
The phone edition reports 6907.222 instead of 6907.221 like the rest of the updated components. I suspect it was a last minute bug fix/issue check-in after the other builds.
Thank to Richard for pointing out there were new updates for Live Meeting and the Conferencing Add-in.
