Good to hear that Office 2007 SP2, which is on the calendar for the first half of 2009, will support the Open Document Format (ODF, 1.1). There is a lot of discussion going on about the support for ODF or OpenXML, especially for governmental use.
From the press release:
"The 2007 Microsoft Office system already provides support for 20 different document formats within Microsoft Office Word, Office Excel and Office PowerPoint. With the release of Microsoft Office 2007 Service Pack 2 (SP2) scheduled for the first half of 2009, the list will grow to include support for XML Paper Specification (XPS), Portable Document Format (PDF) 1.5, PDF/A and Open Document Format (ODF) v1.1.
