If you removed the Metroid license from the game, cut out Sakamoto's story, and made it a sci-fi action collaboration between Nintendo and Team Ninja, IMO a lot of people would be praising it and asking for a sequel.
Team Ninja and Sakamoto should work again on something, just make it an original IP so it's not bogged down by the Metroid mythos and you'd probably get a pretty solid game.
