Google slowly rolling out new web app UI

It seems that Google are slowly implementing a new UI for their web app. The update changes the 'blue tabs' at the top of the site to new 'grey tabs' with pull down icons. To change the type of search, they've updated it to include a drop down grid of all the different search types, and apps, instead of the old text list.
Interestingly, this UI update has only been updated on Web search, Video search, News and Blogs. The older 'blue' interface still appears on Image Search, Places, Shopping, Finance, Apps, iGoogle and Books. Google Apps, like GMail, Google Translate, Google Docs and Google Reader haven't received any form of update either. YouTube has its own mobile web app, and Maps has recently been updated.
