Here is an article reminding us that Novell's Danaergeschenk of Open XML support for OpenOffice.org, is due in late January.
The translators will be available as plug-ins to OpenOffice.org. In addition, Novell plans to release to the open-source community code needed to integrate the Open XML format, developed by Microsoft, into OpenOffice. The integration code is expected to help maintain consistent formats, formulas and style templates across Office 2007 and the open-source productivity suite.
The article doesn't mention any timeline for Microsoft Office's native ODF support implementation.
