"None of this has been decided firmly at all," said David Gerard, a director of Wikimedia U.K., the foundation that runs Wikipedia. "We're deciding this over the next two months... to see if there's anything that makes people cough up a hairball."
It also seems unlikely that Wikipedia would take actions like this, as the site wouldn't even exist were it not for scores of anonymous editors along with the registered ones as well. That said, there's a lot of room for improvement and obviously Wikipedia wants to be taken seriously as an information resource. They are going to need better auditing policies in the future, though how they plan to balance that along with an open editing policy has yet to be told.
