I don't know, isn't Sakurai's condition chronic? Meaning that it can be treated but remains constant over time? The treatments could help his condition, but I don't think that it will be in great shape for yet another Smash game; on top of that, the Smash series gives him overwhelming amounts of stress that would still pose an issue if he were to come back for Smash 5. That's why he stopped work on Kirby; he couldn't handle the stress of it anymore. Sakurai is a total control freak when it comes to game design, but hey, I guess that's what allows him to crank out great Smash games every few years.
