The document discusses the top 5 questions about SharePoint 2010:
1. The release date is May 12, 2010 and will be available on retail shelves in June.
2. Licensing is expected to be similar to previous versions with Foundation being free and Standard/Enterprise requiring server and CAL licenses.
3. Deploying new functionality should wait for SP1, but existing features can be deployed on launch. Migration from 2007 allows controlling the timing and previewing upgrades.
4. Migration from 2007 or 2003 requires recompiling and testing code, adjusting as needed, and upgrading all data (no direct path from 2003). Effort ranges from 50k-250k depending on size.
