Genya Takeda, GM of Nintendo's R&D division, spoke out about the ideas at a recent investor briefing, labelling it as a "natural" move for the console.
He said: "Since an increasing number of the TV sets at home around the world are becoming HD today, it will be natural for a machine to be able to generate graphics that people will be accustomed to see on HD televisions. Since the ordinary TV programs are now shifting to HD, moving to HD appears to me a natural flow."
Another Nintendo exec, Shigeru Miyomoto, added: "We probably cannot swim against the tide. The customers' tastes will become more and more refined. Even today, many customers who have seen HD once say they cannot go back to SD."
However it seems if it was a move Nintendo decided to make, not all games would be developed in HD, due to the increase in development costs.
Miyamoto added: "We have to ask ourselves if HD is really necessary to develop Wii Fit. Won't HD be better for the games like Pikmin? The developers should choose the most appropriate graphical format depending on the software they make.
Interestingly, Nintendo of America president Reggie Fils-Aime has given out a completely conflicting message during a recent interview saying: "Michael [Pachter – an industry analyst] continues to be the only one that believes [Wii HD] is going to happen.
"I don’t know how forcefully we can say that there is no Wii HD".
So what's the deal? It's not quite clear, but it certainly seems Nintendo knows it has to do something to the Wii in order to get it hitting the top of the charts again.
