According to Nellie Andreeva at Deadline, the show, if it goes to series, would be an hourlong drama, a procedural centered around Frank Castle, who instead of being a loner on a one-man war against wrongdoers, is a respected young detective in the New York Police Department.  When the justice system fails, though, Castle throws on his skull t-shirt and secretly moonlights as, you guessed it, The Punisher.

The pilot is executive produced by Ed Bernero, who previously executive produced Criminal Minds and Third Watch.  He also has another series set up at ABC, a paranormal western called The Eye, about a group of Pinkerton detectives who investigate inexplicable events.

The pilot is being produced through ABC Studios.  ABC is, of course, owned by Disney and Disney owns Marvel, which has prolifically minded its characters for cinematic success and is looking to expand more substantially into television.  A new Hulk series has been in the works for some time, with Guillermo del Toro overseeing development, and AKA Jessica Jones has been slowly making progress, as well.

Fox seems keen on superheroes, as the network is also developing The Spectre, a DC character created by Jerry Siegel and Bernard Baily.  Earlier this year, NBC rolled the dice on a Wonder Woman pilot scripted by Ally McBeal creator David E. Kelley, but it was never taken to series and all copies of the pilot episode seem to have been buried deep below the Earth's surface.  Or jettisoned into the void of space.
