orlando writes "Much drama is unfolding prior to the OOXML Ballot Resolution Meeting in Geneva, currently schedule for the end of February. After that there's a subsequent 30 day period while countries can still change their vote. As a result, Bob Sutor is recommending that saving your documents in OOXML format right now is probably about the riskiest thing you can do, if you are concerned with long term interoperability. At this point nobody has the vaguest idea what OOXML will look like in February, or even whether it will be in any sort of stable condition by the end of March. 'While we are talking about interoperability, who else do you think is going to provide long term complete support for this already-dead OOXML format that Microsoft Office 2007 uses today? Interoperability means that other applications can process the files fully and not just products from Microsoft. I would even go so far as to go back to those few OOXML files you have already created and create .doc, .ppt, and .xls versions of them for future use, if you want to make sure you can read them and you don't want to commit yourself to Microsoft's products for the rest of their lives.'"
