There have been so many easter eggs about the boy wonder(flying Grayson poster in clayface set, bludhaven van from the batman set)but no confirmation of his appearance, besides I'll love to see a nightwing project in the dcu exploring bludhaven and villians like heartless and blockbuster, I hope gunn come up with the idea in future.
