Higurashi Kai. I'll definately be following this. The first series was good (not perfect, good) and the second is promising to be even better. The second episode is downloading as I type this.
Zombie Loan. Generic shounen stuff. Reminds of Black Cat for some reason.. Anyway, don't think I'm following this, since I'm put off by the animation style, and the story/action is nothing I haven't seen before.
That's it for new shows. Still following the currently running spring series: Darker Than Black, Claymore and Gurren Lagann.
