That's what i want to know aswell, i want to watch Season 6 already
However i have a feeling that once the rest of s5 comes on DVD next month (atleast in Australia anyway) the might start doing more episodes.....
season 10 you mean, which really shouldn't be labeled because thier is no way its actually season 10. Just viz's version of different seasons separated by box sets. i feel so sorry for you English dub users, your so far behind its unbelievable. I think they are only at like episode 140, just starting the very beginning of the pain arc.
Not to mention disney XD butchers the hell out of this anime, if you don't like subbed and you really have no choice but to watch it English, then i would at least buy the viz box sets.
Although im kind of disappointed that viz is releasing so little of episodes in between each box set, im sure eventually they re release box sets of entire seasons like dragon ball or dbz, but thats probably going to be a ways away.
I am a collector as well, i have all of the Naruto box sets but i won't waste my money on these recent box sets, i'll wait to the series is remastered and re released.
