I would like to answer your question from two different perspectives. Given my development background, the first will be from a developers perspective, and then Ill also try to answer the question from the perspective of a representative of the company that is the platform holder. First, Id like to talk about how much development resources are required in order to take a game and create it in three dimensions.
As long as you are already creating a fully rendered 3D world, all you have to do in order to create the 3D visual effect is to capture the same images with two cameras, one for right eye and the other for left eye. From a development perspective, it actually does not make much of a difference in terms of development costs to create the 3D visual effect.
On the other hand, because the visual capabilities of Nintendo 3DS are more powerful than the existing Nintendo DS, if you are going to take full advantage of the graphics capability of Nintendo 3DS, the development cost is also expected to rise.
Therefore, if developers decide to try and maximize the graphical powers of the system, then the cost would be more expensive than what it is currently for Nintendo DS and may potentially approach the cost of developing Wii software.
Next, I would like to provide my perspective as the president of the company of the platform holder. While I do not think that you simply have to increase the cost of your development in order to create compelling software on Nintendo 3DS, it would also be a lie if I said that any software can be developed without spending a lot of money.
I think its ok to see a broad range in development costs from title to title. I believe its possible for developers who have great ideas to be able to find ways to develop those ideas at a relatively low cost and make the resulting game a hit due essentially to the quality of the ideas.
On the other hand, I believe there will be developers who will use a similar amount of resources to create games as if developing for a home console, and such games also would result in satisfaction to our consumers.
I see the possibility for a broad range of software development costs to increase the possibility of satisfying Nintendo 3DS owners and really appeal to a very broad audience. That would be the ideal situation for Nintendo 3DS. We intend to exemplify this with our first-party titles.
