There's always the new Dragon ball Z kai, Fullmetal Alchemist Brotherhood, Negima Ala Alba, durpy durpy doo. As people have already mentioned theres Code Geass and Umineko no Naku Koro Ni (if I spelled that right). I've heard that this one anime called Berserk was good, but I never watched it myself so I can't exactly recomend it, but whatever. Check out Gintama, it's pretty funny, but a lot of the references are hard to get if you live outside Japan. And although this is outside your preferences, I'll also recomend Sasameki Koto for the heck of it. And for quick reference, a list (perhaps I should just done that...)
