We are likely less than 2 months away from Marvel's The Punisher making it's debut on Netflix. The teaser trailers gave us enough to know it will be November 2017 and if you match that up around the time Marvel's Luke Cage was released, that should put it around November 10th, which would be perfect for the series. November 10th is considered the birthday of the Marine Corps, which Frank Castle aka The Punisher was part of and it's the day before Veterans day. It's not confirmed, but you might want to keep that day open…
Parts of the story are starting to come out as we know we'll see both modern day and back when Frank (Jon Bernthal) was with his unit in Kandahar. Billy Russo (Ben Barnes) will be part of that unit and Frank's best friend… and eventually he becomes Jigsaw. And we know that Karen Page (Deborah Ann-Woll) continue her connection with Frank that started in Marvel's Daredevil season 2. But as for the rest of the world created in the Marvel/Netflix universe… don't expect to see much of it. No ninjas, no hand and no Claire Temple (Rosario Dawson).
Bernthal told EW.com:
We are stripping down every supernatural element. This show is different. It looks different. Frank is a character rooted in the most basic human emotions… He's a comic-book character, but he doesn't fly, he doesn't have X-ray vision. He's an unbelievably skilled soldier who's been very, very angry and very, very hurt.
That said, there is word that another hero will appear in the series, likely one we've not met before. Also, if IMDB is to be believed, Rob Moran will be appearing once again as the street-wise Turk Barrett.
