It seems fairly likely the judge will approve the settlement. First, one of the reasons the judge gave for rejecting the prior settlement was that it was lower per plaintiff than the class lawyers had negotiated with the defendants it had already settled with (Adobe et. al). That objection is now answered. Second, as you mention, judges very rarely reject settlement offers. That's in no small part because when they do, they are often overruled by appellate courts, and judges hate being overruled. As much as class actions lawsuits look like they create massive principle-agent problems to the rest of us, the federal courts are quite comfortable with them, and they have repeatedly applied the maxim that the law favors settlement in the class context. If there is to be class action reform it will have to come from Congress (the Class Action Fairness Act of 2005 was a tiny step in that direction).
