They can't every agree on that. The problem is, the German supreme court just said they can't do it, which has them in massive pretzel. If they accept the ruling, they confirm everyone else's suspicion that the EU is just a German project. If they reject the ruling, then they confirm for everyone that the "leaders" of Europe lied their asses off about the plan to abolish each nation's sovereignty. It's a lose lose. Germany is sick of doling out cash but they want to be in charge. I can't see any way this doesn't end very badly for the EU.
