I attended "How Microsoft IT Plans SharePoint Capacity and Growth" Technet Webcast today. Following are some new features in SharePoint Server 2007 (taken from the webcast):
1. Infrastructure consolidation
> Co-hosting corporate and HostHeader mode sites in the same farm.
> Portals become site collections (fewer databases)
> No small/medium/large farm topology requirements
2. Full fidelity data protection
> Items, lists -> Recycle bin out of the box
> Webs, Sites -> Events that fire before the fact (SPEventReceivers)
> Benefit: Fewer database restores -> larger databases
3. Search
> Windows SharePoint Services: No SQL full-text search
> Common Office Server 2007/Windows SharePoint Services Search Engine
4. Life Cycle Management
> Site collection owner updatable by user
> Enable confirmation and auto deletion
4. Built-in page re-ghosting
> Fixes broken pages
5. Indexes on list columns
