I posted few days ago (here is the link) that the 2nd trailer of 'Harry Potter and the Deathly Hallows - Part 2' will be released within the next 2 weeks.
A Potterhead from Norway emailed WB Norway, and here is the response:
The release date for the upcoming trailer should be mid-June. Either the 15th or 17th.
Usually Warner Bros. released a trailer on the web 2 days before the theatrical release. And we all know that the next WB Film is 'Green Lantern' which has a US play date of June 17. If the 'Deathly Hallows 2' trailer to be attach on 'Green Lantern' then there is a big possibility that the trailer will have an online release on June 15. But let's wait for the official confirmation, I'm just doing some analyses.
