According to Mary Jo Foley, Microsoft is sticking with its plan to end support for NT 4.0:
On December 31, Microsoft will cut the support cord for NT 4.0 Server. Until then, Redmond is providing paid-incident and security-related hot fixes to NT 4.0 Server customers. Non-security-related hot fixes have been available to NT 4.0 Server customers since December 31, 2003, via custom support contracts with Microsoft, but are also set to end as of December 31, 2004.
