Still, I am not sure if the form factor (the size and configuration of the hardware) will be integrated. In contrast, the number of form factors might increase. Currently, we can only provide two form factors because if we had three or four different architectures, we would face serious shortages of software on every platform. To cite a specific case, Apple is able to release smart devices with various form factors one after another because there is one way of programming adopted by all platforms. Apple has a common platform called iOS. Another example is Android. Though there are various models, Android does not face software shortages because there is one common way of programming on the Android platform that works with various models. The point is, Nintendo platforms should be like those two examples. Whether we will ultimately need just one device will be determined by what consumers demand in the future, and that is not something we know at the moment.
Sounds like it was still very much in the air as to whether Nintendo would have multiple SKUs (even more than two) or even just a few as a singular one.
Which direction they ultimately decided upon is a mystery to us right now. Maybe they decided to go the "brother hardware" route with multiple hardware SKUs, maybe they decided on one integrated SKU. This statement from Iwata doesn't discount either scenario.
Just based on the way the Unseen 64 guy, Reggie and Tanabe have spoken about it, I'm starting to lean more towards one integrated device.
You know alienware is doing some interesting stuff where you can take one of their laptops and plug it into a graphics amplifier to create a desktop experience. Maybe the hub or port that you plug the handheld in it will allow you to beef up the graphics a bit such as higher resolution more foliage and some other stuff. LIke they will build the base game for the handheld and upgrade the graphics through that. Who knows? Even what I have said, though I think it is based on good sources, is still just speculation at the end of the day, until they actually make a formal announcement about the system.
