It looks very much like Microsoft have won over the ISO despite the official announcement being delayed until the 2nd. It hasn't exactly been plain sailing for Microsoft with this - with assorted protests still going on - such as Norway's yes vote and questions about how the BSI here in the UK did such a U turn. 

So why the fuss? Open Document Format was approved last year by the ISO and its fans are distrusting and somewhat vocal in their disapproval of Microsoft and the OOXML spec. They suspect down the line it'll give MS a huge advantage and some reckon the spec itself is a little on the flakey side, to say the least. Not like me to use Microsoft and flakey in the same sentence. Oh - just did it again.

Also have a read of the comments on this Register article for a further taster. 

Update - here's the official word from the ISO.
