Could another iceberg be looming for Titanic?

Warner Bros. plans Dark Knight rerelease

News came out today that The Dark Knight will be heading back to theaters, at least IMAX that is, in January. Warner Bros. rationale is that they want it back out to help its awards chances. However, it also gives them an added opportunity to potentially overtake Titanic as the best domestic grosser of all time. So given that The Dark Knight currently sits at $513 mil and isn't done with its current run. Do you think the rerelease will be enough to push it over the top?
