New Google UI?

I just did a Google in Opera and noticed that the UI on deep search pages has changed.

There’s javascript on there to load the "More" menu. Has this been around forever? I’m not a regular Opera user so I’m not entirely sure what’s going on… I can say that Firefox 2 is how it used to be though:

While I can see the design logic behind it (give the logo and search box — the most important elements — most space), it does make the header a little larger.

If this is new, I wonder if this is the start of Google sexifying its network. Historically, they’re pretty stoic when it comes to design but the recent re-re-re-relaunch of ask.com might be scaring them finally into making some sweeping design changes.
