Movies are stagnant though. What is the last great innovative you have seen? I see dozens of movies but I can't think of a truly groundbreaking movie in the last few months. The mainstream movie industry is completely driven by proven sequels and liscences.
Nintendo's traditional games/semi-tradtional are selling higher than they have in a long while - whether on DS (New Super Mario Brothers), or Wii (Zelda should hit what 4 million worldwide? - 2nd or 3rd highest for any Zelda game). The case for semi-traditional games (Mario Party 8) selling better is even stronger. That means either a) The set of gamers you call Nintendo gamers is growing, or b) People who don't love/adore Nintendo on name alone are buying the name. I think it is mostly the second scenario.
Frankly it isn't that hard to appeal to old and new audiences. It happenes every generation. Sony sure as hell succeeded at it from 1997-2006. Nintendo did it from 1985-1996. If you want to stick to the old argument that old experiences are superior since people know what to do with them, go ahead, but look at movies - how many hardcore silent film afficianados are out there? I consider motion control a future industry standard much as sound has become for movies. What is debatable though is how quickly the standard materializes - movies saw a decade like transtion.
