I doubt there's licensing issues since every villain and Spider-Man in this had an action figure released of them in the past. Of course, Electro's figure from TASM2 didn't really look like Jamie Foxx and any Lizard figures don't require Rhys Ifan's likeness but I doubt Foxx would have an issue with it since there was a Hot Toys Electro as well as a Django figure with his likeness.
It could be sooner than that, maybe they're just keeping the info very close to the chest. That Endgame wave that was revealed after the movie came out that had Lebowski Thor as a build a figure was pretty much kept a secret too.
