I am a little late posting this, but the announcement hasn’t taken place yet.

If you publish and distribute your feeds with FeedBurner, you will soon be able to place Google AdSense ads in them.  Previously, FeedBurner used its own advertisements for placement in feeds.  AdSense for feeds is listed as “coming soon”, with a small group of AdSense publishers seeing the new ads as early as next week.  

Publishers already in the FeedBurner Ad Network will continue to see premium CPM ads sold directly onto their content, with contextually targeted ads to fill up any remaining spots.  This will allow the most profitable and relevant ads to be displayed to your subscribers.

Bloggers who aren’t in the AdSense program yet need to sign up for AdSense, where you can control the frequency and rules when ads appear in your feeds.  There are more specifications to come about how to install the ads in your feeds, including placement targeting through the use the Ad Review Center.  

On an ending note, the post states that “there is more things and stuff yet to come”.

All in all, AdSense for feeds will benefit Google the most out of this, at least in the future, with more people using their ad network verses the FeedBurner network or others.  However, bloggers will likely find it more convenient - eventually FeedBurner and AdSense/AdWords along with all the Google services will be interconnected with one main login.
