If you're worried about WIT studio messing with the Remake of One Piece, then I'd say not to worry. The Studio has a great set of anime under its name, and there is no question that the studio will compromise the animation quality. If there is potential to ruin this project, it could be in the narrative planning. Perhaps, to cover more story, the remake might condense more than it should, which could affect the story or major changes in the stories, then I'd be very pissed.
