Check out the HP Position Statement on Standardization of Office Document Formats. It is a refreshing and pragmatic view - that choice is important and ODF and Open XML will co-exist and interoperate. On the ISO standardization process:

"HP believes that the international standardization process is working. This process has already significantly improved the OOXML specification and additional evolution of it will take place under control of the global community if the specification is ratified by ISO/IEC JTC 1. In the current vote on OOXML at JTC 1, HP is supporting an affirmative vote in those national standards bodies in which HP is active."
