Let me clarify, in the Ultimate Comics Universe, Venom wasn't the result of a symbiote, but a bodysuit created by Peter's dad. Since they don't have the rights to do the story with SHIELD and Red Skull, it would seem they're going with the ultimate version where he's a scientist. This is reinforced in the trailer when Peter finds what would become his webshooters in the trailer and Ben remarks it was created by Peter's father.
If they went with the bodysuit version, it would separate it from the Raimi films and make it somewhat more realistic. In the comics, Richard and Mary Parker were killed in a plane crash orchestrated by Richard's benefactor (Norman Osborn). It would be a nice way to tie things together and establish Norman before he becomes the Goblin in a 3rd film.
