Haha, I like how they said "this is absolutely nothing to do with Wii U, seriously, don't even think for one second we're talking about it"
My safe predictions would be:
*Doubutsu no Mori (Animal Crossing, this Autumn/Winter)
*DQX assistant app mention.
*Wii Players Choice selection updated slightly.
My slightly less safe predictions would be:
*Tomodachi Collection (AKA Friend Collection, Mii-avatar life sim)
*NSMB2 level packs.
*Circle Pad Pro LL shown.
*New 3DS XL/LL colour(s).
