It looks like Google is testing a new homepage that will shift some links around and that is about it. There is no official word on if this new homepage was just a Photoshop job or if it is real, but I would say that it looks reasonable enough to be real.
However, I am not sure if I like it very much. Moving the navigation bar to the left side makes the screen look more cluttered in my opinion. I don’t think that this one will make it out of testing.
