Ah, this is sadly true. The problem is that the manga HAS to live the anime in the dust so the anime doesn't accidentally get ahead of the manga. Or something.
Anyway, the whole Inuyasha story is ending soon anyway. The rumor that the anime is ending in September is true. The manga is supposedly ending in December. Which doesn't make sense. But then the fourth movie coming out in December is suppose to be the TRUE ending to the anime series. That rumor has yet to be proven.
