Dattebayo is the most popular fansubs for Anime, especially Naruto Shippuuden, Bleach, etc. for a quality subs they'd make for us fans. From Japanese releases they make English subs just to understand the original shows. I like Naruto Shippuuden very much and every episode it released I download it right away.
A sad news to say that starting 1-15-09 Dattebayo will drop Naruto subs.
It's a sad news to all Naruto lovers and anime lovers.
Here's what the staff of Dattebayo said, click here.
But it's not that bad, Naruto still be aired for free a week after it airs in Japan. Watch them over Crunchyroll starting January for a Pay2View (it's not that expensive).
