Re: The Amazing Spider-Man Review and Discussion Thread (spoilers)
Goody for the Ultimate comics, which also retconned the origin.
It's not a retcon when it's a new continuity (much like the films). Movie adaptations have always drawn from multiple versions of the character from over the years, particularly when, in this case, they're trying to do things differently from the '02 film.
