There have been several rumors about the person in charge of Metroid Prime 4, and Eurogamer seems to know the truth based on a number of sources. The report claims that Bandai Namco Studios Singapore, not Retro Studios, is in charge of the Switch exclusive.

As a point of comparison, the original Metroid Prime trilogy was handled by Retro Studios, a Nintendo subsidiary that is now managing the Donkey Kong Country series. All Metroid games are presently overseen by third companies, with Samus Returns transferred to Mercury Steam and Metroid Prime 4 probably given to Bandai Namco.
Indeed, Metroid Prime 4 is being developed by Bandai Namco [Eurogamer].
