Windows 8 expected in 2011 was expected to only come in a 64 bit version, because Windows Server 2008 R2 was released in 64 bit form only and the next Windows OS was expected to follow suit. However it is now believed that Windows 8 might ship in 64bit AND 128 bit versions, based on the linkedin profile of Microsoft employee Robert Morgan: "Working in high security department for research and development involving strategic planning for medium and longterm projects. Research & Development projects including 128bit architecture compatibility with the Windows 8 kernel and Windows 9 project plan. Forming relationships with major partners: Intel, AMD, HP, and IBM. Robert Morgan is working to get IA-128 working backwards with full binary compatibility on the existing IA-64 instructions in the hardware simulation to work for Windows 8 and definitely Windows 9."
