In the mid 90's Sony fans used the same arguments, when PS1 was outselling N64 after years of dominatiion. Before NPD was what it is today, Nintendo relied only on its own tracking , and therefore was only sure of shipped units. But today, with NPD, the arguments are more heated because the math behind the data is essentially irrefutable (NPD has hard data for 60% of the retail channels and estimates for the rest), which makes it seem like Sony and Microsoft lie more by announcing shipped totals, while Nintendo focuses on aligning itself with Chart-Track, NPD and Media Create.

When there are more laws, there are more criminals.
