Episode 39 write-ups often refer to popular content recaps, such as critical moments in Critical Role, celebrity guest spots on podcasts like Nappy Boy Radio, or chapter teasers for online fiction. They can also refer to technical specs for construction materials or formal employee disciplinary forms.
The door was never really closed honestly. In the situation Nintendo DO want to simply update the existing Wii U/3DS version they don’t have to contract Sakurai, Namco or anybody else to do so. They can do it themselves. Of course keeping the characters in the game depends on licenses.
This is ONLY in the case they want an updated port. They could do a new Smash Bros but either way a 6th instalment will hit Switch eventually.
It just depends how Nintendo want to do it.
