I see your point Mantidor, in fact I somewhat second it in that, the parts of the game that Nintendo is pushing are not that important. 45-minute Hyrule, zillions of hours of gameplay, tons of dungeons: these matter, but there's more to it than that.
Having said that, I think it's too soon to make assumptions about this game. Once we play the actual game, we may feel differently about the "generic" side of it. I've already seen some interesting things in the Twighlight Realm, particularly Wolf Link's ability to sense invisible people and objects. Maybe they're just ghosts (still cool) but maybe there's more going on.
What if Link could sense things that are happening in the ordinary realm while he's in the Twighlight Realm? Forget gossip stones, imagine being able to listen in on people's private conversations from the Twighlight Realm.
