After removing all references to the 64-bit (IA64) Windows XP here, we've spoken to sources close to the company who have confirmed Microsoft's intensions to axe XP IA64. The company wants to focus on Windows Server 2003 editions of Itanium-based systems.
Q: What about Windows XP for Itanium? Is Microsoft still continuing work around that version?
A: Microsoft is excited about the opportunity that x64 technology affords. Because Windows on x64 systems delivers excellent flexibility and choice, while also enabling a smooth migration from 32-bit to 64bit applications, Microsoft believes Windows for Itanium-based systems is a stronger offering in the high-end server market. As such, Microsoft has made the decision to focus its investments in research and development on this new x64 (64-bit extended) architecture and discontinue further investments in the Itanium architecture for workstations.
It is important to emphasize that Microsoft will continue to promote and offer Windows Server 2003 Enterprise and Datacenter Editions for Itanium-based systems, intended for customers who require the highest levels of scalability. For the mainstream server and workstation markets, however, we believe we can best serve our customers needs with Windows Server 2003 Standard x64 Edition, and Windows XP Professional x64 Edition, respectively.
So if you were wondering about what happened to Itanium 64bit Windows XP, there's your answer.
