Didn't need any.
Shadowdropping this game mere hours after the Xbox Developer Direct was pretty much the best decision for a game like this.

Screw months of marketing, screw review embargos, let the players judge for themselves.

For real, Nintendo's probably eying up Chai for Smash 6 if anything; they and Xbox have that console bromance, after all. It's PlayStation who's the "alpha bitch" system.
