This is on Reddit, so take it as you will, but user KokiriEmerald claims that the teaser trailer will be shown “before every single showtime for every single movie at 100 theaters nationwide” next weekend. Their source is a “manager at one of the theaters getting the trailer.”
Obviously, we don’t know if there’s any truth to this yet. It is pretty grand, I guess, but a bit cruel… Unless we’re going to see it debut online as well. (via)
There’s at least one theater chain employee calling bull on this, though they go on to speculate based on the earlier rumors that it’ll debut on TV ahead of theater placement on The Hobbit.
