I'm convinced that most of current search traffic is coming from results generated by the Caffeine infrastructure. But there's turbulence in the ranking water, too - either some new algorithm features or some data instability in Caffeine, we can't really tell as of yet.

The bottom line for me? this is what Google rankings currently look like, and no one has officially announced that the Caffeine roll-out is complete. We may not hear that announcement for a long while It might relieve some uncertainty to hear that announcement, but I can't see a practical difference.

I'm making website enhancements based on what I see right now. I doubt that there will be some new formula that only becomes possible after the official Caffeine announcement.
