One thing that immediately jumps out at me is the following;
Business users will gain greater agility and empowerment with a new highly interactive, web-based data exploration and visualization solution. Introducing new and engaging ways to discover insights through a drag-and-drop interface, smart and powerful data querying and interactive storyboarding to allow users to quickly create and share visual presentations of large datasets.Sounds intriguing - but I'm not sure its in the CTP. Needless to say I'm downloading now...
Its worth checking the release notes here. There is a dependency on Powershell 2.0 - and more importantly no support for side-by-side installations with 2008/R2. There is also no support for XP regardless of SP version.
