Google Webmaster Tools appears to have been updated to include other forms of content good for Google's Universal Search, such as Video (and podcasts, by extension), mostly focusing on Metadata, according to Web Analytics World Blog:
"…Video Sitemaps
The Sitemaps protocol has been extended to support video. You can now include URLs to videos, as well as meta data about those URLs. Google uses Video Sitemaps for their Google Video index, although with universal search, those videos may appear in web search results as well."
If Google is adding and ranking Online Videos, Google Images and Podcasts along with textual Search Results, it makes sense to me there should be diagnostics for that to help the site owner optimize their content - whatever form it's in.
