Much of the core functionality of Oracle is dependent upon the versioning. Microsoft is attempting to duplicate it to put an end to their inability to complete with everything from RAC on down. At it most basic level ... it is impossible for SQL Server to produce a result set consistent to a point-in-time. Which explains to many, especially those inside Microsoft, why they are running their corporate financials on SAP with Oracle. A huge embarrasement for Ballmer & Co.
