I still believe a possibility could be Musou All-Star at launch (it comes out on March 2nd, it wouldn't be that later on Switch's launch), with some Hyrule Warriors characters as Switch's exclusive content.
I think there's a bigger possibility to have exclusives Nintendo costumes than characters. That would be a first otherwise, and Musou Stars is really a game about KT (not Warriors Orochi).
I'm sure we'll see another Nintendo IP Musou soon enough though, after how well HW sold.
