Harry Potter and the Deathly Hallows; Part 2 movie trailer coming May 6th?

I have, I think, after much research, discovered the release date for the
official movie teaser trailer for Harry Potter and the Deathly Hallows: Part 2!

Warner Bros. will want to put a trailer out to the general audience
about 2-3 months prior to the film's actual release date.

So, we're looking at either the last week of April, or the first week of May.
On May 6th, Marvel Studios, now owned by Disney,
will be releasing their newest superhero-based film, Thor.
Rated PG-13, this is definitely a candidate for
the Harry Potter 8 trailer to premiere with.

Thor, being only 70 days before Harry Potter and the Deathly Hallows: Part 2,
would be a good choice. Good, but not great. And 70 days is just enough time
for everyone to get ready for the grand finale of the Harry Potter movie series.
Since our first and only previous choice for the trailer, "Sucker Punch",
was proven wrong, we now put our money (not for real!) behind Thor.
