It won't happen but I'd love for Nintendo to pick them up. Every single one of their Switch projects that I've played has been top notch, in terms of fidelity, performance and overall understanding of the platform and its audience. And they are very good at providing experiences that Nintendo are not capable of providing.
(They were in charge of excellent ports of Alien: Isolation, GRID, Hitman and a few Lara Croft games)
Edit: my bad, had them confused with Feral Interactive who worked on those projects.
Saber did the Switch port of Witcher 3, Kingdom Come: Deliverance, MudRunner, Crysis 1-3, NBA Playgrounds and a few other noticeable projects.
