Just noticed this very interesting ad on a US ad preview search:
The ad on the top right is a photo of a product and the headline names the product. There is no body copy and the display URL appears to read just BuyOnlineNow plus there is a price.As I found this in ad preview, I cannot click on the ad to see where it clicks through to.
On further research this appears to be a continuations of the Adwords Product Listings beta which has been going on for several years now.
Second example of product listings ads:
