I'm going to watch "Arakawa under the Bridge" and "Ouran High School Host Club" . I'm sure they both will be great, because I know them as anime and/or manga.^^
I'll take a look at Hana-Kimi 2 (saw the trailer and ... well ... I'll watch the first ep for sure .. :-/ ) And maybe maybe even Conan but ... actually I don't have any time at all this summer ^^'
I also have my problems with the "boys" from "ikemen desu ne" XDD
