DX hopefuly they will, but i kinda doubt it.. except i dont think the US would go "above and beyond" just to take out the one tailed kyuu.. because they didnt seem to go so above and beyond on much in the English show
The One Tailed Kyuubi Naruto is gonna be a unlockable charahter. For the fact that they're gonna want you to beat a certain about of people or save a load of "money" before doing so. Because people as we see REALLY want to play as him. So I'd say YES to that he'll be in the game, but save your "cash" or play alot of Naruto PSP, thats my say in it.
