Hopefully know more
watchcartoononlin.com has all the episodes and many more anime mostly for free
6 or 7 seasons.
No it is not Manga i just started reading 2 days ago and it is much better then the anime. go to www.onemanga.com and give it a shot.
Shez dead................... no
no!! sorry
All together there's 22 episodes in season 1 of The CW's Vampire Diaries.
Much more dramatic and it would focus more on the horror/monsters aspect.
No there wont be a season 2? Why you say? I am afraid but it's been 5 years since it opened so I don't think it will be a season 2. Also it is sad that there are tons of animes out there that are good and only have 12 episodes. It would be lovely if atleast they would have 3, and an closed ending. I got the feeling when I watched Tona-gura that it was an opened-ending. There are so many good animes out there like this one, shame that it is gone... However you should watch Rosario + Vampire, it is ecchi/romance/action/supernatrual/School. It is quite good, but it only has two seasons. I think there will be more of it soon though (2011) since the creator went bankrupt a few years ago. But now I think he is back on his feet, he will either sell the license or cancel it, but I think he will start working on Rosario + Vampire since it is great. Not sure though.. I hope that there will be more Rosario + Vampire, you should watch it.
maybe we dont know until more episodes
No, but they did continue in comic books.
From what sources say, the anime is officially finished... but about the manga... probably there won't be any more.
