C3 I really haven't really watched the series, but like said it's a good ecchi anime.
Kore Wa Zombie Desuka and it's new season I also haven't been watching.
Tasogare Otome X Amnesia....ohhh I love swim wear. might watch this.
Well enough gaming for me till Dragon's Dogma and Lollipop Chainsaw arrives.
Let's see, C3 Cube X Curse X Curious has an OVA out, if you watched that series you'd might want to see that (I haven't yet though )
There is of course the Highschool DxD Special #2, Kore Wa Zombie Desku of the dead Episode 00, and if you watch Tasogare Otome X Amnesia, episode 04 was really tasty (that is, if you watched it the way I did )
Honestly though, that's all I can say. I'm out of the loop on a lot of Spring shows, so I myself have catching up to do
