If this is true, then we only have one week left to guess. I'm going to guess some unusual routes to be started. In addition to all of the NBO, LYS, ARN, CAI that everyone is predicting, I can see DL starting:

JFK-VLC (Valencia, Spain)
JFK-NUE (Nuernberg, Germany)
JFK-AMN (Amman, Jordan)
JFK-EZE (Has been mentioned long time before. I wonder why it hasnt been started yet?)
JFK-KWI (Kuwait)
JFK-WAW/KRK (Warsaw and/or Krakow)
JFK-NAP (Naples, Italy)

Those are my guesses as to some of the upcoming routes. We'll see in a week if I got any right!
