Directors or whatever they are, tend to do whatever they like best. The guy who did X-Men didn't use the yellow spandex for the X-men, first spidey didn't have web-shooters, Batmobile was turned into a tank, etc.
To be based on the comics or staying faithful to them doesn't seem relevant at times and in other instances, it is.
This old argument is tired. The movie will depend more on other factors, like any other film.
It could go either way but what I do know is that I've seen web-slinging too much all ready and seeing it again just isn't going to wow me right now for a long time.
Though I did like The new Hulk better in The Avengers, just too bad it wasn't a Hulk movie.
