Has this been mentioned here previously? I couldn't find anything in a search.

Found it crawling one of our sites last night - thought it odd, as it was coming from the 66.249.64.0/19 range normally used by googlebot.

The full UA is:

Mozilla/5.0 (en-us) AppleWebKit/525.13 (KHTML, like Gecko; Google Web Preview) Version/3.1 Safari/525.13

Looking for information, I found this:

Google has been caught testing a major new layout to their search results – full page previews of the target site and pale blue backgrounds behind the search results when you hover over them. ... One of the fascinating things about this is that they are highlighting certain sections of the page in orange and expanding the text to provide a snippet of information. This shows that they have the technology to know exactly where a piece of text is on every single web page. The snippets highlighted are not always the same as the snippet in the search results.

The obvious question raised by this, is the effect it will have on click-through rates.
