Wasn't WW originally thought of as a 2008 release that got moved back a bit? (possibly I'm mistaken)
So confirmation on Public Enemies. As I said earlier, it's a good story idea, though I have faith that the writers will drastically reduce the stupid quotient found in Loeb's actual execution of it.
If WW had been released in 2008, then there would have been 3 in 2008. So unless Public Enemies gets delayed to 2010, DC is speeding up to at least 2.5/year.
