yes, for the anime to catch up to the manga at a rate of 2 chapters = 1 episode: fall 2005 (late next year)

but its not 2 chaps per episode...if we devide the amount of chaptes the anime has covered with the amount of episodes that have been aired, we get: 135/78 = 1.75 chapters per episode.

quick calculation gives me 2 years (around this time in 2006) for the anime to catch up.(77 chapters x 1.75 = 44 weeks for the anime to reach chap 212--->44 new chaps released=> 44x1,75=25 weeks for it to reach chap 256, 25x1,75=14, 14x1,75=8, 8x1,75=5, 5x1,75=3 ect
when you sum all the weeks, youll get around 100 weeks, wich is about 1 year. could fluxuate a bit because of inaccuracy)
