I don't imagine them being prominent with Pokemon. I could see it if they made a new Colosseum or Gale of Darkness style game in the Wii U, where there are Amiibos for certain key Pokemon in the game, and all the Amiibos do is let you obtain them earlier, or let you get better ones.

>Amiibo support makes your Pokemon a full 31 IVs across the board when you get it
>Game lets you cross trade with the handhelds
