Eben Moglen is very optimistic. He predicts that regardless of all the noise, GPLv3 will be welcomed by many, just as OpenLogic previously suggested.

Eben Moglen, the law professor and open-source legal expert who has helped lead the revision of the General Public License, is predicting broad success for the upcoming new version.

Let's not forget the endless and aggressive Microsoft lobbying against the GPLv3.

As a side note, I could not help wondering why Microsoft (let alone Novell) attend OSBC, despite the explicit request for a boycott. What is a company that attacks Free software doing at an Open Source event? The scene is attended by the same folks which Microsoft threatens. It's quite absurd.
