There was an article published last week that describes the results of the voting in the technical committee of the German National Body for Standardization (DIN). DIN has been leading the way on a number of areas relating to file formats including the harmonization work between Open XML and ODF.
The article is from the paper eGovernment Computing and it is in German (some folks helped to translate for me): (http://www.egovcom.de/srvinclude/4/1/inews_daily.asp?opt=archiv&red_nr=18255). They report that the technical committee has voted "yes" on approval of the Open XML standardization in an electronic poll. The confirmation was done with a high majority of 14:5.
