The idea of a Metroid Prime Collection is interesting, because it's not straightforward.
Firstly, Nintendo rarely bundles 3 games for one price like that... except that they did with the Metroid Prime Trilogy, so gamers will expect all three together.
Still, remastering all three games is far more work than Nintendo would usually be willing to do for just $60 and I can't see it. So will we get all three, up-rezzed but with no changes to the assets (a la Mario 3d All-Stars), or proper remasters with major improvements but sold separately?
Secondly, how to handle the controls? Many people (like me) think that motion control with the Wiimote is the best way to play the whole trilogy. But there's no IR pointer on Switch, and gyro controls won't play nice with handheld. So... what's the solution? And if it's to use the control scheme from Primes 1 and 2, do you retrofit that onto 3? And what happens to the motion controls then? Or do you finally make the right stick into an FPS style look control?
So what seems like an easy slam dunk release is actually fascinating in terms of how they might go about it.
