Intel: "Itanium Will Survive Even Without Microsoft’s Support" - X-Bit Labs

Windows represents less than 6% of current Itanium sales according to IDC's Q3 2009 server tracker report. Most Itanium users run Unix, specifically HP-UX
At present Intel’s most powerful Itanium processor is model 9300 previously known as Tukwila that has four cores and is made using relatively old 65nm fabrication process. It is projected that in 2012 the world’s largest maker of chips will release 32nm eight-core IA64 chip code-named Poulson, which will also feature micro-architectural enhancements, including new instructions. In 2014 Intel plans to release code-named Kittson chip. Unfortunately, Intel does not make official claims about the future of Itanium at this point.
