Great to have a Nuremburg link. That and the Dresden/Leipzig areas have always been the biggest gaps in the German network.
I do wonder about some routes though.
Will Bremen survive with a daily Hamburg nearby, and I have doubts that Hamburg can sustain up to 4 daily (same as FRA now!) and Berlin up to 3 daily all on A320/B737.
I think Stuttgart should be safe, as it serves a separate area to the announced 3 new routes, it would be like dropping Paris because you've opened up a route to Limoges to serve that area!
But all in all, shaping up to be a very strong German network now.
