Reuters is reporting that the International Organisation for Standardisation (ISO) will announce the result of the OOXML vote on Wednesday.
This is apparently to give them time to let all the national standards bodies, such as our own British Standards Institution, know the result before a press release is issued. However, it would be fair to assume that ISO already knows the answer - it's not that many votes that need counting, after all - so, assuming Reuters is correct, there are two possible reasons why tomorrow (Tuesday) won't be the announcement day:
a) ISO is teasing us, those rascals
b) Because Tuesday is April Fool's Day
I'll let you add your own commentary to that one.
UPDATE (April Fool's morning but not a joke apparently): The chairman of Norway's standards body is appealing to ISO to discount Norway's vote. Because 80 percent of that body were against changing the vote to "yes" - the recorded result. That's the chairman talking. What in the name of Cthulhu went on in these meetings?!
