While we all wait for an official announcement, I'd thought I would post the rather bizarre live action trailers that were released. They are from the 3rd light novel of the series.
"The Boredom of Haruhi Suzumiya"
On 7/7/7 at 9pm Tokyo Time this video was placed on the official website
(haruhi.tv). It shows live footage from security cameras showing figures moving about on a school campus at night. The video show Haruhi and Kyon vandalizing a school field.
Like the events that occured on December 18, 2007, they are very cryptic, and leave much speculation. Some believe that the following videos are from a canceled 2nd season, representing the 3rd light-novel. The original director Tatsuya Ishihara was also working on Clannad, and conflicts may have arose. Yasuhiro Takemoto is the director of the new 2nd season, based on the 4th light-novel.
