In November, Google began testing and rolling out their new drop down menu to Google users. Since then, it has been a very very slow roll out. In fact, I personally do not see the new drop down meny unless I go to Google Australia or other Google localized versions - I am not sure why - to be honest.
Lots of Google users see the new drop down that looks like this:

But what I see and have always seen since November is this:

Ruben at Google Blogoscoped Forums has been flipping back and forth between the different drop down menus. He said Google is testing this new, which is old, version again.
I just think Google has not fully rolled it out yet and people are still in limbo.

I have been waiting for the new dropdown. It's probably because I am a Google Apps user instead of a normal google account user.

I saw it for the firsts time recently when I created a new Google account for a customer. I assumed it was because they had no services yet (no gmail, places, adwords).
