Geek Tyrant reports:
Sony and Marvel were actually going to let this awesome little Easter Egg be a part of The Avengers.
The only reason that the Oscorp building did not make the cut was
because it needed some up-conversion to fit into the skyline for the
film. The digital Manhattan seen in Avengers was already done, so this awesome superhero skyline was scrapped.
Props to Geek Tyrant!
