Google Reader was too much integrated into the Google brand and also had a very easy and clear migration path to other services. You like it or not it's expandable.
Feedburner on the other hand would be harder to migrate. They might do the same as they did to SketchUp and just sell the service to someone that is interested in making a business out of it.
