The decision to bring Pokemon to iOS and Android this summer seems to be final but Nintendo would like to remind you that although the made the Pokemon franchise great, the games are actually built by the Pokemon Company (of which Nintendo owns a minority) and that those guys can do whatever they want.
Nintendo spokesman Yasuhiro Minagawa said that Nintendo would never sell Nintendo-licensed games on non-Nintendo hardware but, like Metal Gear Solid, Sonic, and the like, developers were free to branch out into whatever platform they wished. This, in turn, means that characters like Mario and Zelda will never, ever, ever appear on iOS, no matter how much you beg.
