Iwata: There will be games that will be enhanced by the Wii Motion Plus as well as games that can only be played with it. Users will need four if they have four controllers, but we’re going to try to offer it for as little as possible. We haven’t announced the price yet, but the cost of making the Wii Motion Plus is not that much, so I think we can make it very affordable.

We posted a Wall Street Journal Interview article yesterday about no new accessories in the pipeline.  This was another tidbit from the interview where he mentions Nintendo’s goal to make the Motion Plus as affordable as possible.
