What animê shows are really popular right now and what are some brand new ones the only new one i know of is o espaço dandy

Well, a new animê that is popular that I know of is Noragami. Kill la Kill is pretty popular as well, and it's new.

magi the kingdom of magic is a new one I have heard of so far

If you talk about 'famous', naruto is the most famous animê I've ever known...
The animê that I think are old enough are Yu Yu Hakusho and City Hunter...
I also don't know any new one other than that weird anime, o espaço Dandy... I only know 2-3 upcoming animê shows....

The ones I know are:
One Piece
naruto Shippuden
Fairy Tail
Bleach
Death Note
Fullmetal Alchemist: Brotherhood

A lot of fãs say that Attack on Titan is worth watching. I haven't seen it myself, but I might soon.
