Spidey is up against it and this new trailer fleshes out the previous trailer, showing why Peter fights in a home-made suit, a bit more on why the Vulture is doing what he's doing and shows some cool new stuff about his suit and even debuts spider-bots, along with a whole butt-load of action and quips.
And also more Tony Stark. I wonder (and hope) there'll at least be a few more Avengers cameos (we see Cap in the trailer to fleetingly)
This movie is gonna be wild, I wish I could pre-book my Imax ticket now already!!
