I received an email that they are changing their layout. You'll be receiving notifications when fans interact with your page or posts. There will also be a place to showcase photos at the top of the page, a news feed, and the ability to like and post on other pages as your page. All pages will be automatically upgraded on March 10. Hope that info helps.
