SM3 suffered from a multitude of flaws, basically there isn't any reason why aside from trying to meet the release date of the film should the game have been put out. All in all, if this game doesn't succeed (which at this point, Spidey games are walking that fine line) Activision might as well give up the rights to the character and hand them over to a developer that could do the character more justice, which may be highly unlikely as far as they are concerned.
Now, going based on the scope of the film and the fact that this version of Spidey is more "grounded" within the realm of reality to say the least, I think the game should follow suit. It would be nice if Activision would hire someone like Cyrill Raffaelli to do motion capture for Spider-Man, especially after watching both District 13 films, the guy is very well skilled in martial arts and parkour which both could benefit when applied to Spider-Man thus giving him more "natural" movement during combat, that's just my opinion
