I've been looking at microformats and particularly RDF's ever since I attended the Yahoo Searchmonkey party that seemed to put a lot of empphasis on the language as a way of pulling more data into the SERPS based on sites that are already making use of the language, and the ratings systems used for resturants and cars was a prime example.
I suspect that this is one of the in-roads, the making use of microformats, that are leading to a semantic web, much like what berners-lee envisioned, and with the recent talk of wolfram¦alpha providing a "unique" way to search for content, that Google too, see's a shift coming, away from static pages being displayed as a result in the SERP, to a more dynamic result, being comprised of tagged data..
Yeah, it's the own site's initial content that has been tagged and formatted, but I think it may extend beyond that to Google eventually displaying the compiled data from a variety of sources, all while on the SERP..
I guess the alternative is to not include the new format, Google displays what they feel is relevant or to come up with a tag much like NOODP but for NOExtendedDesc.
