I've heard that Xenoblade came out in Europe in August.
OMG...Could it be...could we really get a Villains x Shulk reveal trailer? Granted, I reckon the villains would be reserved for secret character status, but...can anybody imagine a huge trailer confirming the likes of King K. Rool, Ganondorf, Ghirahim, Ridley, Dark Pit, Meta Knight, Wolf, ROB, and Mewtwo all in one swoop in an epic battle against Nintendo's heroes, only for the power of the Monado to change their destinies? Heck, just so long as they can fit Ness and Falco in for good measure, then I'm good.
As for Chorus Kids, I reckon if they go the route with the Shulk x Villains trailer, then they, Wario, Ice Climbers, and Jigglypuff will be confirmed in their own separate trailer.
And then, at the October Direct, Sakurai reveals 8-Bit Mario as a playable character!
But in all seriousness, I'm predicting Shulk, Falco, and Ness getting revealed together in one trailer, Chorus Kids, Wario and Ice Climbers in another, the villains will have their own trailer, and then Jigglypuff, Mr. Game & Watch, ROB, and 8-Bit Mario all get confirmed together in the final trailer.
