I highly doubt it'll work... Most petitions to localise games don't work to begin with, besides, it's Inazuma Eleven... There's not that many countries in America interested in football besides Latin American countries...
And to be fair, from a publishers point of view, those countries, while they might be big, they're not exactly famous economic wise... And localising it for the entire USA would be a waste of money as well, since most people wouldn't buy it to begin with. In Europe, football is the king of sports and countries like Spain, Portugal, England, Germany, France, Holland, Italy and the list goes on. Personally I'm not a big fan of football, but I like the game because it's a good RPG, but most people here buy the game because of the anime, which airs on TV as well (there was even a contract in England, that they delayed the game release over there so that they'd only release the game after the anime had been going on for a couple months).
Basically, the way LEVEL 5 takes care of this game in Europe is:
- Release Anime;
- Wait a couple months;
- Release game;
- Wait until anime finishes;
- Announce another season;
- Release new anime season;
- Wait a couple of months;
- Release new game;
- Wait until anime finishes;
- Announce another season;
- Release new game.
That's how it's been working in Europe so far, that's also the reason why the games take so long to have the sequels released.
