While it's been assumed by many that 4A Games' upcoming shooter Metro: Last Light was coming to Nintendo's Wii U, it seems that deduction was premature as THQ's Global brand manager Mark Madsen has admitted that the title is no longer a confirmed Wii U game.
Madsen, in an interview with Digital Spy, did concede that a "port" could still happen, but that it would also be "correct" to say that the game is no longer confirmed for the Wii U.
Not at the moment, it's not in development…If it does happen, it won't sim-ship with the other SKUs, but if the opportunity arises we'll take a look at it.
