Hey I just thought of something - the Abilities Plus and Minus will be a lot better in tripple battles. Say you have one Pokemon with Plus and two with Minus: at the very least both of the Pokemon with Minus should get 50% boost in Special Defense. The interesting question is whether the two Minuses will stack, i.e., will the Pokemon will Plus get two 50% boosts in Special Attack. This would be more than a + 2 Boost, it would be a 2.25 boost (1.5 * 1.5 * Original Special Attack). Plusle with 663 Special Attack (605 if Timid) before LO or Specs sounds pretty dangerous. And if we're lucky Gear will evolve and keep those abilities, giving us a better Pokemon (or at least a greater variety of Pokemon) to execute this strategy.
Also I've been looking over some of the old Pre-release pictures and I'm starting to think Hihidaruma is NFE. On its own it looks pretty big and intimidating, but it's only like 4 ' 3 " tall! You'd think a big flaming gorilla would be at least 6 feet tall. Also it's pretty light, and in the triple battle picture where it appears with the mole and the Zebra, its Sprite is rather small (though this could just be because of the camera, but it's still about the same size as the two other NFEs).
