Unfortunately, Electric, the deal between Marvel and Sony does mean that some (not all.) characters can only be used by one studio or the other, and unfortunately, Sony happens to hold major villains like Norman Osborn and Eddie Brock.

In fact, back in August, I heard a rumor that Kevin Feige was lobbying Sony for the film rights to Mysterio and Kraven the Hunter to be the villains in the Homecoming sequel (HA!! I CALLED IT!!! I F***ING CALLED IT!!!!!), but Sony's giving him a hard time because they have those characters planned for their own buddy-cop styled film.

So, yeah. The deal does restrict some major characters, regardless of weather Marvel wants to use them or not, from appearing in the MCU.
