I voted "don't know, don't care," because, well, I don't know, and I don't care. Sasha is cute. If I have the good fortune to get a Sasha card, I'll probably scan Sasha right onto my island. I wonder if the new villagers will be locked to amiibo cards like the Sanrio ones, and never appear on mystery islands. I hope not.
Also, I keep seeing people referring to Shino as female, but Shino has horns/antlers, and all of the female deer in the game have no horns (other than Chelsea, who is clearly wearing a bunny ears headband as her "horns") so... is Shino going to be the first female deer with horns, or a male deer? Is there some clear evidence one way or the other in the Direct? Once again, I don't know and don't care, since I don't particularly like Shino's design, and I probably wouldn't move Shino onto my island if I had the opportunity. But now that this thread has brought up this topic, I'm curious.
