hahah! no way are they going to put out a switch ir bar. Are we gonna hold the right joycon upside down for that to work? lol I would enjoy seeing that happen tho. I guess anything is possible in this crazy timeline.
The joycon's gyro is already capable of being used for skyward sword. Game already has a 'recenter' button just like Splatoon 2, but it brings up that fairy lady. Hopefully they will change that.
Same goes for Metroid Prime trillogy. They can use the gyro and use the 'recenter' button instead of an ir bar. Splatoon and TWEWY proved gyro aiming works just fine if you can recenter the joycons.
