Some things you all might wanna know about the new anime:
http://mblg.tv/mooocha/entry/834/
-Kaito won't be appearing early on
-Hisoka won;t be perverted but instead be a "brave man" (not too sure what that means)
-Less violence (kinda obvious)
-Togashi himself will be supervising the anime
Well I;m not too surprised about hearing that the violence level will be lowered though hopefully not to the extent of Toriko. Hisoka being changed a bit is a bit disappointing, but Hisoka being well...Hisoka, I don;t know how well he;d have flown on a daytime timeslot for kids. Kaito not appearing early is fairly forgiving since he;s not all that important early on. I will assume that the flashback with him in the first chapter will be kept in though.
Since Togashi is supervising the thing I think most of these changes won;t end terribly, though I guess we'll see how it goes(I probably won;t notice too many of the changes since my memory of the beginning of the manga is somewhat vague). At least it means this might actually have a legit ending.
That's his main trait, I'd rather want him to stay the same since there is another way to 'avoid' his perverted behavior.
