I have a feeling that Nintendo cancelled Metroid: Federation Force, Project Robot, Project Guard, Lost Reavers (in the West), Genei Ibun Roku (in the West)

At Treehouse E3 they already said that they just begun localisation on Genei Ibun , so I bet it is nearly finished (since it is still considered as an early 2016 release in the west). The Project-Games are obviously cancelled. Metroid is still a thing.

It is just Nintendos way of work, announcing a title and not talking about it for a long time, no surprise here.
