indeed they are due for a new metroid game. I'd love to see a Super Metroid 3DS. nintendo games never comes out on PC unfortunately
but if they revamp the Metroid fusion like Capcom did for Resident Evil that would be interesting. going in style of Metroid: another M scheme would be good i think I like that game even though hearing Samus' voice and her progression gave me a mix feeling on how her strong character is. but we all get used to it by just loving the gameplay XD
