It appears that ISO is now working on “harmonizing” OOXML and ODF, and the Norwegian protest continues, though switching that vote would not be decisive.

However, there does appear to be an EU anti-trust investigation regarding their lobbying, (Note: the link is two months old, and so might be mooted by the vote).

My guess is that the fat lady has sung.

My other guess is that if OOXML were to become a real standard, Microsoft Office would not be certified as complying, if the experience of Internet Explorer is any guide.
