You've had plenty of time to upgrade to Google's Universal Analytics by now. They opened up access in March of last year, but some may have been hesitant to do so fo fear of the unknown.
Universal Analytics is aimed at large enterprises, such as Premium customers and those who want to work with APIs. It offers the ability to tailor Google Analytics to your specific needs, integrate your own datasets, and as Google puts it, "ultimately get a more complete vision of the entire marketing funnel."
Google has a new video out answering some questions people have had about the upgrade, which might make the process less intimidating for you if you've been considering making the jump.
They put out another, longer video about upgrading a while back, which should help you out even more.
Here's Google's original announcement about Universal Analytics, which talks more about its features.
