Google Adsense: New EXPANDABLE ADS!!

Have you checked the Adsense post about the "Expandable Ads"? Well, I must say that Google is making the Adsense more effective and hence, making the Adsense users- publishers more happy.
Some points from the post:

• You are automatically eligible for the new ads!
  
• The expandable ads are currently available for advertisers in U.S. Only.
• Publisher's earning CPC will be calculated not only if the user clicks the ads to expand, but when a user visits the advertisers page.
• You can use competitive filters like other existing ads

From the post:
Expandable ads will be served as third-party ads and will be created by Google-certified rich media vendors for the top display advertisers in our network. And like other Google ads, you'll earn based on whether the expandable ads on your site are priced on a cost-per-click (CPC) or cost-per-impression (CPM) basis. Keep in mind that you'll generate earnings from CPC expandable ads when a user visits the advertiser's landing page, and not when a user simply clicks to expand the ad.
