Metroid Prime 4 is now in development. Dreams really do come true. No other info is currently known. The new game will mark the first entry in the Prime series in a decade, as the original trilogy concluded with Metroid Prime 3: Corruption on the original Wii in 2007. The Prime subseries debuted on the GameCube in 2002, and was especially notable for successfully translating the iconic, moody exploration of the original Metroid games into a three-dimensional, first-person experience.
