What happens when/if The Dark Knight passes Titanic in money made...?

[Incandescence]

Worldwide: http://www.imdb.com/boxoffice/alltimegross?region=world-wide

Titanic is at 1.85 billion (Not adjusted for inflation), while TDK is at 596 million.

Domestic (USA): http://www.boxofficemojo.com/alltime/domestic.htm

Titanic is at 600 million (Not adjusted for inflation), while TDK is at 393 million.

TDK's probably going to pass Titanic in the US by the amount of money it grosses, but not in ticket sales. I don't see much of a possibility of it passing Titanic's worldwide gross at all, inflation or not. Time will tell, I guess.
