I think that we will either get a direct in probably March that will be a 'mini' (about 20 minutes). Or Nintendo will not do a direct and just announce there remaining Switch exclusive games through trailer drops and announcements. Most are going to probably just be remakes and remaster so they don't really have to have a direct. I think that the next Switch will be announced separately from where they announce the remaining Switch exclusives. I think the Switch 2 will have some sort special event in march or April, With a more complete show case over the summer.
