Is Google Testing A New Layout For Displaying AdWords Sitelinks Extensions?

Google seems to be testing a new style for displaying Sitelink extensions with AdWords Search Ads.  This new way of showing the sitelink extension gives more space to the ad on Google searches. Both the links and the descriptions are being shown horizontally in just one column.
