Oh yes, you are right, he did mention about Haruhi. ハルヒ is Haruhi's first name. I am not entirely sure if it is about next season during next fall though, but I think it did mention about a CONFIRMATION next fall, and I think that means we will know by next fall when the second season will come, but I am not sure.
It also mentions about Zero no Tsukaima second season next fall, but unfortunately I can't make out the details.
Sorry I can't be much of a help.
