Rumors have been rampant that the Sinister Six would appear either in this movie or in the 3rd Amazing Spider-Man film...this shows that Sony has something in mind in those regards.
The following tweet from Marvel Spider shows a very interesting screengrab:

The grab shows us Connors, who was the first film's villain, Dr. Morbius and Venom. We know Sony has been talking about expanding the Spider-verse and I'd imagine Morbius and Venom would be two characters they would potentially develop. In this instance, we may see the Ultimate version of Venom instead of the 616-alien symbiote version we saw in Sam Raimi's Spider-Man 3.
