Is 32-bit Windows coming to a end?

Bill Laing has been quoted as saying that “Windows Server 2008 would be the last 32-bit Microsoft server operating system.”  Apparently, Windows Server 2008 R2 will be 64-bit only.  However, the story for the desktop may be different.  Alex Heaton says "A few folks took Bill’s comments on Windows Server and applied them to Windows Client deriving that Windows Vista would be the last 32-bit operating system. That is an incorrect extension.  While Windows Vista includes both 32-bit and 64-bit and there is a growing community of drivers for 64-bit Windows Vista we have not decided when Windows Client will follow Windows Server and become 64-bit only."

So, it looks like no more 32-bit server operating systems.  However, the same cannot be said for the desktop.  Yet.
