TSR's Super Smash Bros Thread|SWITCH HYPE TRAIN NOW BOARDING

[SchAlternate]

So someone at Smashboards pointed out an interesting theory:

What if the build that was sent to ESRB wasn't the final build? I mean, Nintendo should've learned with X/Y that leaks are bound to happen anytime, so in case anyone dared to do that, the ESRB build lacked some of the characters in the game, perhaps including the ones that would generate the most hype (Mewtwo, Ridley, god knows what else).

So yeah, food for thought.
