Apple released an iTunes Movie Trailers app last year, so you could watch movie trailers from iTunes directly on your iPad, and that app has just been updated with the ability to stream movies at a higher resolution (probably around 1080p, since that's the usual format for these things, but we can't be sure). This way, they'll look even better on the Retina Display of your new iPad. You can go right now, and watch movie trailers like The Avengers, Prometheus, and more over there for free.
