Suzukik posted a thread at WebmasterWorld sharing a possible new Google test. Google seems to be testing showing descriptions near or under the Google Sitelinks.
Suzukik posted screen shots on his blog that he allowed me to share here.
Here are some examples, I know they are in Japanese.
I personally cannot reproduce it in either Google Japan or Google U.S.
Google is constantly testing features, so I would not be surprised if this is another Google test.
Forum discussion at WebmasterWorld.

It sounds like a good idea but I don't think it will work out. This will just push down the rest of the SERPS and make the #1 spot then entire first page.

Where does the description come from? You can only put 35 char in the text field.

That is some serious SERP real estate for the first result!
