"one could reasonably expect that the cost of a terabyte will be reduced from about $1000 today to $100 in 2007."

...

"This is the core of our vision which we think of as Your Data, Any Place, Any Time ."

"Our investments will be across four key themes:

  • Continuous Availability and Automation (SQL Server AlwaysOn Technologies )
  • Beyond Relational
  • Dynamic Applications ( SQL Server Everywhere Edition)
  • End-To-End Insight"
