I love Smash, but this is kind of weird and sad to think about, lol
Like I wasn't expecting him to come back to Kid Icarus, Uprising was very clearly a one and done deal, but I figured once Smash was over he'd begin working on a new project akin to Uprising or Meteos.
But by the sound of things...it seems like he's just going to keep working continously on Smash until the day he fully retires from game making. He even directly acknowledges that he's been working on this series consecutively for 7-8 years.
I'm probably going to be nearing my 30s when Smash Ultimate's DLC support is finally done...
