Question

Is there going to be a second season of The Melancholy of Haruhi Suzumiya?

Answer 1

Yes. the date hasn't been decided.

Second season:

The new season of the anime series was first announced in a full-page advertisement of Asahi Shimbun on July 7, 2007 in Japan. Promotional videos for the new season included a live action sequence inspired by the "Bamboo Leaf Rhapsody" chapter from the third novel which depicts Haruhi and Kyon breaking into school grounds with the footage taken from surveillance cameras. On December 18, 2007, the anime's official website, haruhi.tv, was replaced by a fake 404 error with five form input fields. If KNSAK (the initials of the SOS Brigade members' family names, with the exception of Kyon, whose initial is taken from his nickname) was inputted, a fake xterm interface opened with messages by "YUKI.N". At the end of these messages, the enter key could be pressed, which redirected the page to an informational page about the new season. As reported by Anime News Network, "the 'disappearance' of the website on December 18 at 4:00 a.m. (Japan Standard Time) is a reference to the pivotal date in The Vanishment of Haruhi Suzumiya, the fourth volume in the light novel series and an apparent indication of which novel plot the anime project will adapt."

Answer 2

Not sure if I can be of much help, but it has definitely been implied that there will be a season two.

Nothing I can find has confirmed this or given a date.

This seems to be the only informations given, and if true its been 8 months with no word? They are taking their sweet time.
