Just because they track
US and Canadian sales doesn't mean they can't disaggregate
US and Canadian sales.
Just another example, this time from Variety
According to industry tracker NPD Group, Sony sold 197,000 PlayStation 3's in the U.S. in November, following the console's Nov. 17 launch.
Microsoft, meanwhile, sold 42,000 units of its new HD-DVD player add-on for the Xbox 360 in the U.S. last month.
Microsoft's HD DVD peripheral landed in 92,000 US homes since it was launched in November, but comparing its success to that of Sony's competing Blu-Ray is tough. Researchers at the NPD group tallied all sales for the add-on over the last two months of 2006.
The only figure specifically pertaining to "North America" is the 175,000 total players in 2006. To correct that, as Canada population is about one tenth that of the US, we can have an estimate that it was 158,000 for the US and 17,000 for Canada.
That would give 66,000 standalone HD DVD players for the US in 2006.
The 100,000 standalone players figures is also for the US. That would yield 34,000
players sold in 2007 for the US.
