Thomas Whitehead - In a turn of events that shouldn't surprise any followers of Nintendo, an anonymous source of reasonable repute has recently been quoted as stating that a big-name HD remaster is on the way to Wii U in 2015. We'd suggest this isn't too far off from saying something rather obvious such as "Nintendo is making games that haven't been announced yet", such is the business logic that makes HD re-releases / remasters a likelihood. They can, given the right material, represent an easy win for the company.
It's perhaps remarkable that we've had so few of these HD titles to date. The success-story and only prominent example is The Legend of Zelda: The Wind Waker HD; as of the most recent formal update from Nintendo, it had sold 1.22 million copies up to 31st March this year.
