Personally i hope this is true. The Spidey franchise was in danger of plummeting into the same abyss the 90's Batman films did with far too many villains competing for screentime.
I never understood why they did that to begin with. Burning up all the super villains simply depletes the fuel for good stories.
It at least made some kind of sense in Batman Returns. Catwoman isn't big enough to be the only villain in a Batman movie so they paired her up with the Penguin. However all teamups in the next two were just dumb. They completely wasted Bane who should have had his own movie.
