Facebook Sponsored Stories will appear in news feed in 2012

This could be the massive news for Facebook in 2012: introducing the Sponsored Stories in the news feed.
As everybody knows our bull eyes on Facebook are focused on the news feed. So adding sponsored stories in the news feed will definitely generate huge amounts of clicks and increase the conversion rate of the ads.
It will probably be the most expensive ad placement on Facebook, and therefore add a new significant revenue stream for Facebook. It will be a as well a way for users to monetise their friends with their profile or their fans with their fanpages.
This is how it will look like.
