I'm in Germany(although not for the fight) for that fight so I'll be interested to experience it over there.
The only German commentator who a) knows what he's talking about or b) will admit when a home fighter clearly got a bent decision is on German Eurosport, so you'll never hear him on live TV unfortunately. He's like a German Terry Wogan almost, with his exasperation at dodgy decisions matching Wogan's despair at Eurovision Voting.
On the plus side, here it'll be on RTL I think, basically free-to-air, non PPV. And maybe at a decent hour of the day (although I haven't checked, but the Americans would rather watch paint dry than the Klitchkos).
