but this is my prediction
there will probably be 2 villians, with harry being one of them. and the venom saga is going to begin.
at the beginin of the movie peters gonna find the simbiot and is going to be bind with it. the movie will end with peter killing harry as the venom spiderman then seeing that the simbiot is bad peter will part from it. that is when the simbiot will join with eddie brook, and we have the camera close with venom being the villain in the 4 movie.
