Someone on the PPRuNe forums predicted this route a few months ago. They also mentioned Oslo & Bergen. The map below is taken from the airports Masterplan 2035.

Ambitious plan.
I could see Turkish trying Istanbul to compete with Emirates for far east traffic, but Delhi, Beijing and Hong Kong seem unlikely to me. If New York didnt work, I'd be amazed if Atlanta did
Munich should work though, reasonable connections with Lufthansa, and the tourist traffic, should be sustainable. If the airport can sustain a Dusseldorf flight, Munich should work a treat.
Budapest would be class and probably sustainable, but I dont know who would be interest enough to operate it. Ryanair maybe?
