I am kind of expecting Team Plasma to appear at least, just not right away like how long it took for Team Galactic back in D/P to appear if I remember correctly. But N, I am not so sure of.
This is what I don't understand, why do people think that Team Plasma can act without N at all, that they could go the saga without one appearance from their King? If you vouch for that, you're vouching for a repeat for what happened to Magma and Aqua.
