I highly doubt that after bringing the series overseas that they would not bring any of the games over. That would be stupid.
Not really. They just wanna get more sales. I can't see any IS businessmen going, "Stupid American. Give you casual mode cause you not Japan. I fart in your general direction." Besides, the mode (let alone the game) hasn't been announced here, yet, and Japan also gets that mode. They won't just get more sales in America/Europe/elsewhere. They'll most likely get more sales in Japan, too.
Also, analyzing your quote, would it not be an insult to Europe as well? No you're right; they can't strategize their way out of a paper bag. Kidding, of course. :P
