Nicely put man, I believe that house (as a whole genre) also has people waiting for the tune to break, but in its most recent trends (synthpop, electroclash, tech-house, progressive house) you can obviously see that the focus is put often in the leads/hi hats/cadence while in full on for instance, the bass has the biggest impact IMHO (not saying that the rest of the layers dont have any participation, just that the bass is essential). Thus, giving the crowd instant gratification, not letting the song to develop in a way that the rythm slowly puts you -inside-, its more like this crazyness going on that puts your blood pressure up in the sky.
Also the way the songs are structured, you can obviously see the effort to create a big climax after the song goes bassless or kickless just to explode or break putting the whole thing in your face.
A good listener will hear a song develop and take form, creating the feeling that you need to listen to the whole album to get the idea of the artist, not to explode every fucking 5 minutes so everyone has the crazy high, thats why full on doesnt appeal to old and experimented listeners.
