What Happened To This Google Redesign??

So back in 2011 I was excited to see Google was planning to get rid of the black bar across all of their web services, making navigation on every page the Logo with a drop-down menu, search bar, and then G+ profile/share/notifications on the right. It was more beautiful and made more sense than what they have now. All I can find is that it was cancelled...but WHY?!?!
