It's a new Vulture, we're assuming. Given that BND's chief ideal was 'everything old is new again', we've had new versions of Kraven and the Goblin, effectively, and we're getting a genuinely unusual Doc Ock revamp in the next few months, supposedly.
So either Toomes is getting a severe makeover, or it is a new character. And it isn't like the Vulture is without precedent for being replaced. Blackie Drago, is it?
