In der Google "Webmaster FAQ" steht, dass Microformats & Co. wohl weiterhin interpretiert werden:

If you’ve marked up your content for rich snippets using microformats, microdata, or RDFa, then you're already familiar with the process. schema.org works the same way, using the microdata markup format and a vocabulary that is shared by all the search engines and that supports a wide variety of item types and properties.
