Unfortunately AnimagiC is in Bonn^^ not Berlin. That's a difference of about 6 hours travelling via ICE.
The next AnimagiC takes place from 29.07. till 31.07.2011 though.
But there is also a Con in Berlin called MMC (Mega Manga Convention) this year which takes place from 21.10. till 23.10.2011. Never have been to MMC yet, but last year Animaco, which is quite similiar to MMC I believe, was nice.^^
AnimagiC is larger though.
