Google's navigational bar is now available for all international versions of Google, even though the services included in the bar are different from one country to another.
There are also changes for the US version of Google (or the global version, if you like). Google removed from the list of services: Blogger, Labs, orkut, Patent Search, but added YouTube, the most popular property after Google Search, and a link to the More Google Products page.
Even though this makes Google's interface more consistent, you'll still find services that have an old navigation. Some international Google versions have different services: for example, Google Brazil and Google India include orkut in the main list of links because orkut is very popular there. In many countries, the antiquated Google Directory is still on the homepage.
