I did find it interested that, back when the initial announcement and trailer were released, Link was still obviously sporting a Twilight Princess look. I had thought that, because of the strange design tendencies of the series that tend to fluctuate, each main Link in Smash Bros would always be based off the latest incarnation of Link. But with Zelda's confirmation, it's blatantly obvious that it's also her TP look, even though that game is well over being the latest Zelda title released.
Perhaps they just like the brown hair more? Or it could just be that SS style wasn't fitting to make it as the prime representation of the Zelda series in their eyes, and Toon Link in there to appease other players who think differently.
