Just seen this on the SharePoint Team Blog found here

• SharePoint Server 2010 will be 64-bit only.
• SharePoint Server 2010 will require 64-bit Windows Server 2008 or 64-bit Windows Server 2008 R2.
• SharePoint Server 2010 will require 64-bit SQL Server 2008 or 64-bit SQL Server 2005.

I wonder what this means for all those development houses out there who have to go and replace laptops, with new copies of Windows 2008, SharePoint 2010 and SQL Server.
