It already does - or are you saying that the Xenoblade Chronicles remake is a port rather than an exclusive. The thing with releasing New 3DS exclusives is that it doesn't make any great business sense for Nintendo to aim any game for only a small fraction of the 3DS userbase rather than the whole lot. That's why I imagine their current approach of having New 3DS exclusive features in regular 3DS games is the way they will continue.
