According to Porthole magazine, NCL will be holding a press conference onboard the Norwegian Sky on April 17th. Initial rumors are that they have finally sold the ship. However, I respectfully disagree. I doubt they will announce that they have sold the ship. Those announcements tend to be quick pressers that are released and not much fuss is made from them. Besides, why would they drag the press to a ship and show her off, only to announce that they have sold her.
My guess would be more Breakaway/Getaway announcements, or something new they have in store for the sky.
