For anyone who didn't notice, GPLv3 dd3 is out: http://gplv3.fsf.org/gpl3-dd3-guide
I've put up a side-by-side diff of dd2 and dd3: http://fsfeurope.org/projects/gplv3/diff-draft2-draft3.en.html
Brett Smith of FSF has already posted a clarification about the bracketed phrase at the end of the 2nd last paragraph of section 11 (Patents): http://www.fsf.org/blogs/licensing/2007-03-28-gplv3-grandfather

For anyone that can make it to Brussels for April 1st, Richard Stallman will be there to talk on GPLv3: http://fsfe.org/en/events/gplv3_improving_a_great_licence
...and for any other information, just ask, or take a look at FSFE's page: http://fsfeurope.org/projects/gplv3
