...gerade gelesen WPF wird ein Ribbon Control erhalten:

Another oft-requested control is the Office Ribbon, and I'm sure you'll be pleased to know that we're also shipping an implementation of that control, also out-of-band, before the end of the year. The ribbon will be fully implemented in WPF, will be compliant with the UI design guidelines and have an intuitive collection-based API.

und sogar ein DataGrid. :-)
