Implicit DataTemplates
This feature enables the following capabilities:
ContentPresenter DataTemplates can be selected based upon the content type.

Custom Markup Extensions
Custom markup extensions allow you to run custom code from XAML. Markup extensions allow code to be run at XAML parse time for both properties and event handlers, enabling cutting
edge MVVM
defined freeform layout or multiple column layout.
forward and rewind and variable speed playback at common speeds (1.2x, 1.4x) – a very common scenario for enterprise training content. The MediaElement.Rate property supports the values 8.0, 4.0, 0.5, 1, 4.0, 8.0. Note : AudioPitch correction is not present in the Beta but will be added for the final release.
