DCU Original Animated Movie #6: 'Superman/Batman: Public Enemies'

I just found a story at Ain't It Cool News (via Robot 6 @ Comic Book Resources) that confirms that the sixth direct-to-video DC Universe Original Animated PG-13 Movie (following Green Lantern: First Flight) will be Superman/Batman: Public Enemies. The film is said to be in production already with Bruce Timm as Executive Producer. It is expected to be released in Fall 2009. A synopsis follows:

United States President Lex Luthor uses the oncoming trajectory of a
kryptonite asteroid to frame Superman and declare a $1 billion bounty
on the heads of the Man of Steel and his “partner in crime” Batman.
Super heroes and super villains alike launch a relentless pursuit of
Superman and Batman, who must unite – and recruit super help – to
stave off the action-packed onslaught, stop the asteroid, and uncover
Luthor’s devious plot to take command of far more than North America.
