I truly wonder about this . The last 2D Metroid game we got was Metroid Zero Mission in 2004 and since then we got absolutely nothing. There was the rumored DS game Metroid Dread, but it is unknown if it is cancelled or not. Sakamoto said a few years ago that Nintendo would return to the game after they are done with Other M, but we haven't heard anything about this since then. It's probably better this way since Sakamoto is not good at directing games anymore.
It is pretty much confirmed that the next 3D Metroid game will come for the Wii U at some point, but what about the 2D Metroid games? Are they dead forever?
