Spiderman's suit should remain the Red/Blue that he has always traditionally wore.
The black symbiote didn't come on until later, but if for some reason Sam Raimi feels obligated to introduce the alien symbiote, then I can only imagine Spiderman waering a black suit...that is capable of turning into any outfit.
Hopefully the writers don't feel the need to go the route of the Batman series of movies by changing the costume to the extreme every new movie.
If it the plot has anything to do with Venom. Superior would be correct, because when Spider-Man goes into space with Dr.Connors, Spider-Man rips his suit. And has to create a new suit with materials from whatever planet they were on. So chances are if the movie has anything to do with Venom, and wants to be true to the comic book. Spider-Man will also have a black costume.
They don't use CG to improve the web on his costume RJ 馃槅
They make the changes themselves.
He will NOT have the black costume. Accept it.
They will make minor changes to the suit in Spidey 3, probably change his web symbol like they did with the first and second, they'll just give his suit more detail and improvements.
