I believe poor Nintendo is fucking afraid of releasing a new Metroid game.

It's even possible to launch a Metroig game which would make people happy? Unless it's Breath of the Wild good people will find something to complain. Not retro. Too retro. Samus too talky, Samus too quiet. New NPC sucks, new gameplay is not good, etc.

Or they could pick the same man-hour and launch a Mario / Animal Crossing / Zelda / Splatoon or even risk something new which isn't tainted by negativity at this point.

If I was Nintendo, I would just bid my time and work on other stuff instead of risking a financial loss on a IP which seen to only bring complains.
