If you weren't at E3 2012 this year then you probably missed the 140 foot wide trailer, but don't worry we got you covered:
The resolution on this trailer was 6336x720. Pretty intense and definitely had people stopping in their tracks to check it out.
The trailer was mostly a collection of footage many people had already seen, but shows you the length in which publishers go to grab your attention over their competition.
Think the trailer is widescreen enough?
