People like new technology. I bought it just to play Xenoblade.
Although the C-stick is excellent for camera controls in all of the games that allow that (and quite a few more on the way I imagine). The adaptable 3D is also brilliant.
There's also Binding of Isaac, which is new 3DS exclusive. And I imagine a few more indies will come out for it, given that they announced Unity support for it.
