Exchange Server due out in 2006

"Andy Lees, corporate vice president of marketing for Microsoft's server and tools business, revealed the ship date Tuesday."

This suggests that Exchange 12 will arrive sooner versus later.  It was previous suggested the release date might not be until early 2007.

Lees also indicated that Exchange 12 will support "both the 64-bit extensions and the dual-core technology."  I don't think that includes Itanium.
