Microsoft announced that XML will be the default file format for Office 12. I’ll look more at the details and what this means to OpenOffice etc. when I get a chance, but this is certainly great news and another major step forward for XML in general and Microsoft’s support for it. It looks like Microsoft has addressed (full Microsoft press release) the main concerns that critics exposed during the OpenOffice debate we have been covering here and in our conferences. Tim is impressed!
Update: Dan Farber has some additional info from Microsoft.
Update 2: Dan points to info from Rick Schaut on Office 12 Mac XML support.
