Yeah as great as gyro is I do miss the Wiimote pointer, and I'd love it if they found a way to make that workable in the next system. It worked wonders in games like Metroid Prime 3/Trilogy, Sin & Punishment Star Successor, RE4, etc.
While I wasn't a fan of the game itself for how barebones it was and not being into fighting games, ARMS had an interesting implementation of motion and I'd love to see that kind of thing adapted to like a mech game or something.
