Google announced on the Google Webmaster Central blog that they have rolled out the product rich snippets globally to work in any language. So now no matter where you search and what language the site is in, if it has the product rich snippets and Google approved them, they will show up.
But more exciting for me is that they expanded the rich snippet testing tool to really let you do proper testing. Previously, to test your rich snippet markup, you had to upload the code and run a test on the URL in this tool. Now you no longer need to point Google to a URL, you can just copy the HTML into the box and run a test that way.
Google said:
Second, we've updated the rich snippets testing tool to support HTML input. We heard from many users that they wanted to be able to test their HTML source without having to publish it to a web page. This is now supported by the tool, as shown below.

Get the right snippet and see CTR sky rocket. Can see google knocking this feature on the head in the future when this is spammed and clusters their results.

More like soon Ron, I've seen so many sites already abusing this with 50-100 reviews that are all 5 stars on their services. It's just a matter of time when internet users find out that the ratings are fake and stop trusting them. Spammers are destroying ruining the net for all of us=)
