Here is some new things regarding Record Management in SharePoint 2010:
- In-place Records Management (In this method, the documents stay in the current location, and they are classified as business records)
- Document Sets
- Persistent Document IDs
- Content Organizer
- Compliance Details Menu Option
And also a very nice improvement in SharePoint 2010 folders will now be able to act as true parents, the idea now is to set metadata at the folder level, so that the child objects can inherit that information.
