I'm not sure why everyone thinks this is going to lead to uncut DVDs or something like that.
4Kids just said they aren't making anymore episodes, but they still own the rights.
Which means first they'd have to sell them to another company. Then that company will have to start dubbing the whole series from scratch since the episodes were edited up BEFORE the voice actors worked on it.
And since thanks to 4Kids, One Piece is now a proven failed property. So all the odds of this happening have been reduced.
