Sakurai Says His Work on SSBU Ends With Sora amiibo
In a Twitter post, Masahiro Sakurai stated that the last bit of work he needed to do for SSBU was a Sora amiibo.
Has he said what's next...?
No. Though I think he said his YouTube channel will be stopping soon as he'll be starting a new project.
I wouldn't be at all surprised though if he decides to oversee an inevitable Ultimate port/expansion for Switch 2.
