I think you are overly optimistic here. Data retention is still perfectly legal and I'm sure it will continue in many European countries. They are just no longer required to have a data retention law. It now depends on the lawmakers and the constitutional courts of the respective countries to take actions. But I agree with you, in Germany data retention is now very unlikely to happen. For the countries that have implemented it already, it's going to be very hard to reverse, though.
