That means the Silver Sable and Black Cat movie will be bringing in major characters from the Spider-Man comics.
Not only is the studio releasing an R-rated Venom movie, but they just announced that Gina Prince-Bythewood is set to direct Silver and Black, the spin-off based on the characters Silver Sable and Black Cat.
So, if Sony uses them in Silver and Black, that would have major implications for that happening within the MCU.
It also seems as though Silver Sable will be taking the lead, with Black Cat being a very strong supporting character who joins up with her.
