At last week's Ballot Resolution Meeting in Geneva, the national bodies had 1,100 issues to resolve. They resolved 20 to 30 substantial issues and adopted fixes for about 200 trivial issues, and then had a bulk vote on the rest. Only 10 countries agreed to cast a for/against vote and the result was 6-approve and 4-disapprove. 2 of those countries might actually have been ineligible to vote, in which case the result would be 4-4.
So there're about 900 problems with MS-suggested fixes which were ticked as approved without discussion of whether the fixes fix the problems, whether the fixes clash with each other, whether the fixes are themselves problematic, etc. A mess.
Despite this, people who were in Geneva tell me that it still looks realistic that OOXML *will* get ISO approval. So it looks like there's one more month of work to do before the real decision.

(I hope my above summary is accurate, but I'm no expert on this and I've been wrong before - the links are in the blog entry are more authoritative sources.)
