Australian billionaire Cliver Palmer's says his $432 million replica of the Titanic will set sail in 2018.
From Sick Chirpse:
Titanic II looks virtually identical to the Belfast-built liner that sank in April 1912 after smashing into an iceberg on its maiden voyage, but its modern improvements and hyper-vigilant staff should ensure that history doesn't repeat itself. That's the plan anyway.
The ship is four metres wider than the original (in order to meet modern maritime safety regulations) and the hull will be welded rather than riveted. It will sell first, second and third class tickets, have 9 floors and 840 cabins and will accommodate 2,400 passengers and 900 crew members. It will also contain Turkish baths, a swimming pool and gyms.
Here are some images of the Titanic II. They make the ship look as welcoming as the world of Bioshock:
