So is there an official response from the editor about an addendum or retraction then?

If you really want to get a reaction from them the best approach is to start an emailing campaign against any company who advertizes with them, or any company who has an upcomming game release (telling them not to send a review copy of the game) ...

You'd be surprised how one complaint to an advertizer can have more of an impact than thousands of complaints to an editor

That and ask Metacritic and Gamerankings to pull that review, as it was clearly not a fair review.

While we're at it, as them to reconsider Daemon Hatfield's IGN reviews for the Wii, now that he's admitted what he thinks of that system.
