K-On - Episode 13:
Very disappointed. Episode 12 would have made more sense to end it on, and even then wouldn't have seemed like a real ending.
Guin Saga - Episode 1:
Looks quite good, pretty weird, weird getting used to the animation, but it looks promising.
Eden of the East - Episode 1:
Utterly mental by the looks of it, but I have a feeling about it, like it's going to be something good.
[edit]
forgot to mention, to add to the mental of EotE, at least in the first episode there are a lot of Americans in it, with actual American voices :O and Noel Gallagher does the opening theme.
