Brian the author of the revolution themes made an announcement that I didn’t saw coming. He pulles all his themes of the market starting November 1st 2008.
So if you want to buy any revolution theme this is the moment.
He will start to make new themes that will be licenced under the GPL butto protect the integraty of the current premium themes he will no longer be offering those. His reason for doing this is that he feeld he owes the WordPress community his whole business and the opportunity to leave his job. So as a thank you he will start to create free themes. Nice thoughts and completely in spirit of the open source community.
