Nintendo recap of the Nintendo Direct Partner Showcase

I feel it would be for Switch 2. Probably won't be a launch title, since they have only released Metriod Prime 1 remake, and I don't think they will release remake 2 and 3 in one year, and then release 4 right after that.

That's just a speculation though.

This was a partner showcase, so no news on first party whatsoever. Still I believe we are ways off till it's announcement.
