For anybody with satellite tv wishing to watch from home (without subscribing to, or paying for, Sky Sports Box Office), the match is being shown live and FTV on German tv - the Klitschko brothers are big stars in Germany and appear regularly on chat shows, game shows and the like.
The commentary will obviously be in German, but (for non-German speakers) you can always turn down the volume and listen to the radio commentary, a la TMS.
