This would be a good time to bring Metroid to the 3DS, I loved the Prime series, it bridged the gap between 2D and 3D perfectly! I wouldn't mind seeing a Metroid Prime 4. Also this may seem weird, but Super Metroid is such a memorable game, could you imagine if they retold the story of Super Metroid in a 3D game, all the while tell us about our mysterious protagonist. I don't want a remake of any Metroid Prime games, the graphics look great to me, they may not be the best thing out there, but they don't disappoint either.
