What? This is an insane idea to begin with. It's right up there with Compaq buying Digital and HP buying Compaq. Companies with too much money and no clue do things like this. Apple has too much money but absolutely no lack of critical thinkers who would realise this is a dumb idea.
Right now Apple makes platforms. Developers develop for those platforms and make lots of money. No shortage of good games on iOS, in case you haven't looked. And while I haven't seen anyone playing a Nintendo portable in a year or so, I see Android/iOS games everywhere. Nintendo haven't even got a worthy console in this generation. What does Nintendo even have that Apple would want?
Should Apple want Nintendo's IP (characters etc. - and I don't think that is Apple's style at all, just the only vaguely valuable thing there) they just have to wait a bit longer. If they did want Nintendo, the only risk to waiting would be that some other company would snap them up first. Nintendo certainly isn't going to worth _more_ in a year.
