Richard Stallman announced this on Saturday: http://technocrat.net/d/2007/3/24/16783/
Draft 3 is the result of 8 months of public comment and committee discussion.
On April 1st, Stallman will speak on GPLv3 in Brussels. We'll be recording it (fingers crossed) and I hope to make a transcript. Event page: http://fsfe.org/en/events/gplv3_improving_a_great_licence
