I'm increasingly getting excited for this. I am, justifiably, doubtful of its success. I am also unfamiliar with the studio. That said, I am still excited to see how it will turn out. There's so little information out right now that all sorts of thoughts are running through. It's very easy to mess this up. The style of One Piece is irreproducible in a live action setting without looking goofy. With a possible budget that is even higher than Game of Thrones they can't risk alienating mass audiences who are would easily pass off a goofy looking show over the more popular serious looking shows. Any adaptation from one media to the other will have a need for change to be properly adapted, so I'm not disappointed in that. In fact, I'm excited to see how they'll handle adapting One Piece to live action, keeping the goofyness of its style without become too cartoony. I'm also excited to see how much they'll change. I don't doubt that they'd change a lot regarding the female characters. Not fundimentally, but in the sense where Oda apologetically makes fanservice a point. I doubt all the main women will be big and busty. I'm also excited how they'll adapt and localize jokes. They have a lot more freedom regarding this compared to when 4kids localized the anime.
it's late but I just wanted to put my thoughts together. hopefully we get more info soon
