Nintendo UK big man David Yarnton seems to share the enthusiasm of his American and Japanese counterparts. As he told MCV magazine, Nintendo still has quite a few potential customers left, and they fully intend to sell them things:
We really have only scratched the surface in terms of the number of potential users still out there. [...] As long as there are still people who do not play video games, then we still have a lot of work to do.
When the total number of DS systems sold hits 6.7 billion, you know Nintendo is ready to take a rest. (Or release anther hardware revision.)
