New Google Search Page?

I was just reading this article comparing Google Search and Bing and I decided to check out both pages. I usually do most of my searching via the Chrome ‘Omnibox,’ or whatever it is called. When I went to www.google.com I noticed that it had a different, slicker appearance than I was used to. The buttons were styled diferently. And then, after about 3 seconds, more content faded in. Anyone know anything about this? How long has it been like this? There are some screenshots in the review I was reading and they don’t even match the new look and feel.

I think they might also be doing some browser sniffing, because it looked better in Chrome than in IE – and not just the normal stuff. It looked like different styles were being applied.
