Beautiful can mean a couple of things... you could be talking about graphics, or you could be describing the gameplay as "beautiful", as I do with a few games. As far as graphics go, I don't really care. Twilight Princess looked more realistic, yes, but we don't need Zelda games looking too realistic, so the graphics don't really matter to me. They could have Ocarina of Time graphics and I wouldn't care about the difference, and I wouldn't say either looked more "beautiful". Twilight Princess was essentially Ocarina of Time graphics with a few simple changes to make it seem darker and the like. Of course they also tweaked them up a bit.
As far as gameplay goes, however, I certainly think that SS will be more beautiful than TP. At least, I hope it is. We don't need something worse than TP. TP was a pretty darn good game, but I'd love to see an even better game.
