New theory, since the grappling hook is here, if you analyze closer to the grappling model, it says "Prototype 2 Web-slinger" This means that Miles Morales is coming soon during this season, the grappling hook does resemble quite a lot to the comics when Miles first gets his web slinging moves, during the coming days there will be web bouncers forming around a specific part of the map (I wonder where cough Daily Bugle cough), and there will be more graffiti to match with the upcoming movie, so it's safe to say that the Grappling hook, or should I say, Prototype 2 Web-slinger proves that Miles Morales will appear on the map as an npc confirmed.
