We've already seen censorship in Pokemon ever since it was released in America in 1998.
Toshiro Ono Manga will never be re-released in its original form or will we ever get a manga like that.
Jynx is now purple
Pokemon TCG artwork passes through American approval before released in Japan so they don't have to censor the cards anymore.
Rei's skirts in Colosseum was made longer and top was no longer a crop top.
Iris was made the travelling character of BW because the female protagonist was deemed too sexy..
No more Misty in a Bikini after Gen I. Relaxed with Gen III with May but got too much "heat" for her constant Bikinis and was heavily toned down for Dawn and later they became non-existant.
Dialog has been altered like the perv outside Erika's Gym or to remove death.
Game corner eliminated.
These are just off the top of my head, these aren't things the Japanese care for but they self-censor to be able to sell their product overseas where they get tons of cash from. You can bet that if Nintendo had never taken the chance to release RBY in the states that Pokemon would have continued to be more Japanese and less western when it comes to content. It'd still be a kids show but sexualization isn't a big deal there.
