Next SharePoint – Microsoft SharePoint (Server) 2010
The next SharePoint Server will be “Microsoft SharePoint Server 2010”. No more Office in the server product names. That will make it much easier to talk about the products. We can forget SharePoint 14. Welcome SharePoint 2010!
You can read the announcement at the official SharePoint Blog.
The SharePoint Services will keep the name and have many new features. What exactly these features might be, is still in the dark 🙁
