Goddamn I hope this is true so fucking bad. I finished Metroid Prime and started 2 but by that point I was kind of done with the Wii U. I really want to play the entire trilogy. It would be especially cool if the visuals got a huge overhaul rather than just a straight port, but either would be amazing. I hope they can find a way to make the gyro controls as accurate as the motion controls were for the Wii collection.
With how much improved the Joycons must be over the Wii controllers it can't be too hard.
