If you are going to bring up a Metroid game, I can assure you, it would have sold just as badly, nevermind a new IP.
The blame for the sales failure is directed at the WiiU itself, not the game.
I didn't mention Metroid. And Metroid is a franchise that can be limited by userbase. DK was according to some a mainstream 6M seller franchise on Wii, so userbase must not be a problem.
