Amsterdam–Berlin takes 6 hours now by day (7 hours from Brussels). Something which might improve to 4 hours eventually. That's OK, but if I have the choice between getting a sleeper and stepping out of Berlin Hauptbahnhof (Tief) at 6:30 or arriving past 14:00, I know which has my preference. The service is planned to eventually continue to Dresden and Prague by the way, further increasing its usefulness.
