I'm excited to tell everyone that OneNote 2010 and SharePoint Workspace 2010 (formerly Groove) will be added to the Microsoft Office Professional Plus 2010 release. We are not announcing any information about consumer SKU changes just now.
OneNote 2010 provides a comprehensive set of tools to accommodate how people and teams work today. With shared notebooks, organizations can gain even more from SharePoint investments - OneNote becomes the easiest place for teams, including teachers, students and faculty, to quickly swap information and stay on track. With this release, it offers new and improved ways to capture and share collective knowledge. OneNote 2010 facilitates collaborative editing in wiki-like ‘living documents.
So overall, we're really excited to see OneNote included in this upcoming Office 2010 SKU.
