Recent buzz from the Japanese blogosphere and 2ch has all but come to the conclusion that the current “The Sigh of Haruhi Suzumiya” arc will run for 3 more weeks, coming to a total of 5 full episodes for the story.
The widespread consensus is mostly based on the calm rate Kyoto Animation has been adapting the story thus far, neatly fitting exactly 55 pages of the 278 page novel into the first two episodes of the arc so far.
The rest of the factors being presented are: There are 7 more episodes expected for the rebroadcast of the series, 4 of which are repeats from the first season, the original Episode 00 (The Adventures of Mikuru Asahina) should obviously come after the “Sigh” arc for continuity reasons, and there appears to be no time left for a proper adaptation of the fan-favorite “Disappearance” arc.
Taking all that into consideration, the idea that the next 3 episodes to air will continue and finish the current arc, and the final 4 airings will handle the still unaired quartet of episodes from the first season seems probable, although fan speculation has already proven to be wildly inaccurate once this season.
For those who would not mind reading Japanese webpages, New Akiba has collected a fairly sizable number of links regarding the discussions.
Just where this all leaves longhair Haruhi is not clear…
