Unless Paul Allen (microsft co-founder) wishes to add yet another massive ship to his PRIVATE fleet (currently his largest is over 400ft) then, it will have to be a company. I doubt anyone would solely splurge a hell of a lot of cash on a ship. And there i am afraid is the problem, the Titanic 2, would be to reliant on it's legend, and yeah, course I, and no doubt many of you would want to go on it. However in the long run, I.e atleast 30 year's, it wont be econimically viable, so no company that want's to make money (let's not kid ourself, it's all about money) would do it.
