Update: At its Paris Games Week 2017 PlayStation Showcase Sony revealed an all new trailer for the new Spider-Man game. The trailer had a large focus on the game's story, and appeared to confirm that Miles Morales will have a much bigger part to play in the game than his appearance in the previous trailer suggested. 

Does this mean we'll have two playable Spider-Men in the upcoming game? Only time will tell.
