I think we're all reading too much into this report. It sounds like they're writing a pilot, rather than green-lighting and casting a series.
Pilots are meant to be test-beds, and that is what this sounds like.
If they make such and it doesn't work; it doesn't work. Tons of pilots are made and never sold/go to series.
We're only hearing of this one because of it's connection to major high-profile films.
That said, as many issues as it will surely have, I still can't help but be intrigued simply because it's Nolan's Gotham. Even sans Batman and Gordon.
I do wonder if there is anyone from TDKR they could get to be in this, though? Any cops? Maybe Foley?
