Reading the story in the link, it seems he would develop other characters too, mentioning Black Cat by name.
"And I’d certainly develop other characters in the Spider-Man universe, which is what they are trying to do, I know. Black Cat deserves her own movie series. As for the superhero genre generally now, I am stunned at its viability, its quality, its longevity, and its ability to grow and deepen. I think they’re great. I was so continually wrong about where superhero movies were going that now I am just an audience member, thrilled to see them continue to improve."
