Office 2010 - default file format ballot OOXML or ODF

Something I missed in the Office 2010 beta’s – apparently Office will ask you for the default file format you want to use - Office Open XML format or OpenDocuments Format - the first time that you open it.

This is apparently part of an agreement of Microsoft to commit to more interoperable applications. In Office 2007 Microsoft supported ODF through a separate Sourceforge project but now you get it built in. In september 2008 Belgian government decided to standardize on ODF – so know they can use ODF and still use Office 2010.
