Changes to AdSense Ad Format - Icons and Mini-Search

Several people reporting seeing a new format to Google AdSense ads today.  Apparently some ads now have a mini Search field for Users to type in keywords for more relevant ads to appear.

Some other reports on seeing logos or "favicons" in some AdSense Ad formats this morning as well. 

IMO, these options are intended to please both the advertisers (Adwords) and the publishers by providing more options that hopefully convert better. So far, not seeing any news in the Google AdSense Admin area, but I assume that is because these new formats are in a trial period, but seems like lately the new AdSense features roll out fairly quickly after the rumors and reports start flying...
