But, to answer your question - Sun's supposedly going to roll out a new version of the exam "soon". From my conversations at JavaOne with some of the folks involved in the process, they're trying to decide what to do about it still, and are also debating upgrade path for those who already have the certification. There's no estimated date yet for when these will be put into place.
