In a recent interview with True Gaming, creative director at Crystal Dynamics Noah Hughes spoke about the reasons why Tomb Raider isnt coming to Nintendos new console.
Im always a fan of the Nintendo systems, in particular they really push interface design, and from a game design perspective its fun to play with new interfaces. Having said that its something that I think we would want to tailor the experience to if we were going to do it.
Hughes went on to speak about how the development team tailor made the game for the PlayStation 3, Xbox 360 and PC and, because Wii U is offering something so unique, it would require more than just a basic port.
All three of those are really trying to deliver roughly the same experience but delivered best on each platform, and I think something like the Wii U often asks you to do something unique based on a unique interface. Thats something as a gamer I love but its something you dont want to do half-heartedly as a developer.
Seems to me it's the same BS excuse Capcom gave for the PS Vita not getting Resident Evil Revelations.
Although if this is true then the sole reason why WiiU isn't getting nearly half the games the 360 or PS3 are getting then it's probably due to Developers thinking they HAVE to do something with the Tablet. (IE: Developers are afraid of the New Controller.)
