I was re-watching the trailer again, I am wondering if the person in the Ronin suit, if that's Maya Lopez. I mean it could be Clint, but we do know that Maya was the first person in the comics to become Ronin. Plus it seems that Clint is surprised to see Ronin on TV. I mean unless it was him and they were reporting it and that's why he is having that reaction. In addition he did state looks the past is caught up with me, so it could be him. But again I feel like it might be Maya in the suit not Clint.

Looked like it was Kate Bishop from the look of the trailer.

Kinda hard to tell because the face was covered but you could be right

It is Kate.

I wonder why she is wearing the Robin suit. I think it would have made since if it were Maya

I was so hoping to see Vincent D'Onofrio's Kingpin appear at the end but I guess that if he is in the show they're saving it like they are with CC appearing in NWH (not 100% confirmed).

3 episodes. Will share scenes with Clint and Echo. Comic like size. Vague about Daredevil Netflix continuity.

Fisk spent the five year timeskip getting fatter

Seven. Daredevil Season 3 is late 2017, this show is set in Christmas 2024.

Lets not forget. Last time we saw Kingpin he was in custody. So we have to assume he is either out there again, or he is still in prison. If we assume he wasn't snapped, then the seven years might just be enough time for him to come out of jail.
