This popped up on my FB feed. It may be a ways away, but a new class of ships with innovative fuel technology to curve greenhouse emissions. Still sounds like a mega ship too at 5000 passengers. 

 

I know its more of an advancement with fuel technology and eco friendly ships, but the devils advocate in me says, they are more mega ships, which will reduce the opportunity for ports... Will cruise lines produce small ships anymore with the roll out of the mega ships???
