A DigitalPoint Forums thread reports spotting new Google AdSense units being tested. It appears Google is mixing a typical text ad unit with what are called link units.
Here is a screen capture taken from the forum thread:
Notice the links at the bottom of the ad. You can click on the image or go to the thread to see a full size version.
These ads are also being tested on other ad formats, as you can see on page two of the thread.
I was unable to reproduce the ads, but they seem to be real.
