Let's get one thing straight.
If you don't expect the next/final Smash Direct to go as follow:
"That's all for the roster of Super Smash Brothers Ultimate."
*Sakurai pauses*
"Oh, well, not quite, actually. Please, take a look at this."
*X characters gets revealed ala Mewtwo*
"X has joined the battle....but they're not ready quite yet. However, to anyone with a Nintendo Online Subscription, they'll get them for free. They'll be available to people without one at a later date."
"The team and I will continue to support Super Smash Brothers Ultimate through downloadable content like this after the game has launched. We hope you enjoy the new characters and stages that we have planned."
*Direct ends*
Then you're a fool. The Online Subscription is an easy grab for Smash fans, because you're going to HAVE to get it if you want to play online. They're going to sweeten the deal by giving you the first DLC character free.
