Metroid Prime 4: Mouse and Motion Control?

Now that the Switch 2 is officially a thing, and we have seen the rumored optical mouse attachment, do we think that mouse-and-thumbstick controls are likely in MP:4 in addition to motion and standard control stick?

It seems incredibly likely that motion controls will remain in the joycon as the system will be compatible with the majority of the existing library, but my initial thought about a new mouse mode was that it would be great for FPS.

Well, and that I also want a new Mario Paint.
