I also recomend a look on the two flyers who describes the product, and the comparative table between the 2007 and 2010 versions:

Edition Comparison Table
In my opinion, the most interesting features available on this new version are:
- Fluent ribbon interface (Office 2007-2010 like)
- Create “User Defined Actions” using the drag and drop workflow designer (if it allows to export this actions)
- Export workflows to Visual Studio 2010 (it’s very useful to customize the workflow, adding new capabilities)
- InfoPath form generation/support (no idea how it works yet, there are no info available, but sounds nice)
I hope I can play with it soon! :)
