Yeah I don't expect anything on the level of Mario Wonder, but they'll almost certainly be some significant software announced for the back half of the year, which is looking very scant right now with no first party title dated beyond June.
There'll be some third party stuff as well; support has wound down a little from its peak in 2019-2022, but even so this year we've already gotten the likes of Grounded, Pentiment, Kingdom Come Deliverance, Prince of Persia, etc.
With the June Direct plus all the other shows/events happening in June, there should be a fair few Switch announcements.
