Although the judges were a joke, I see very little likelihood of a rematch unfortunately, especially not away from home for Abraham. Sauerland just wouldn't let it happen and it would cost Hearn big bucks to get Abraham over and I don't reckon he would take the financial risk.
Sadly, there will always be home decisions, Ricky Burns never gave a rematch over here when he got a dodgy draw against Beltran. It happens everywhere I'm afraid.
