Eh, D. Gray-Man showed some potential to become great in the beginning, but IMO, it became clouded with way too much filler and unresolved subl-plots, which really dragged down its quality. The manga is better, but from where I left off, it was basically going in the direction of the typical shounen, which is why I ended up taking a break from it. Overall, DGM has some nice ideas, but also has tons of cliche characters and enRAB up becoming a disappointment. But, that's just my personal opinion.
You know, as far as One Piece goes, I have yet to see FUNimation's dub of it, and I'm curious to see how that turned out.
Also, despite me not being too big on it in comparison to the awesome TV series, it would be nice if FUNimation were to license and dub the YYH movie. Unfortunately, I can pretty much say that such a thing will never happen when even the cheap and affordable season box sets haven't sold all that well for FUNimation (at least not in comparison to their other titles).
