Photoshop Elements 11 now uses the same engine as the full version of Photoshop, which will likely mean faster execution of commands and the potential for more complex actions. The UI is more icon based now, as you'd expect with a consumer-oriented solution, bundling several more complex actions into simpler ones. When you're editing photos, there are three different levels of complexity you can choose from. So, if you're a beginner, you can have the simplest options. If you're an expert, you can have more control. It seems like a rather elegant solution to help accommodate a wide variety of users.
