For me it would be Gankutsuou, Steins;Gate, Chuunibyo demo koi ga shitai and Higurashi no naku koro ni (Kai) mainly. I don't care about dubbing though, for me it's perfectly fine if they just sell the dvds with subs and maybe a little extra goodie like a poster if they're in the mood. ^^
Fist of the North Star deserves a much better and far more complete dub than it received when it first came to the US. I would also like to see the rest of the Lupin III franchise dubbed into English and released on Blu-ray.
