So, your point was that PS3 is relatively more popular in Canada than it is in the USA, but still a good deal less popular than the 360. Or is your point that the PS3 is now the more popular console in Canada? You have some data for the former, but not the latter.
This is why these sales threads suck.
Okay, but it also shows another thing, with those two datapoints (not much I know) the trend is upwards for PS3. OTOH, the PS3 trend in the US is also upwards, and a sharper incline too.
We can also speculate that Canada 2009's PS3 Slim tipped the balance further, how much is hard to say. OTOH, this year's XBOX slim probably brought it back again.
But yeah, unless he is simply saying PS3 sells relatively better in Canada than the US there's no much hard evidence beyond that to credibly sustain the other argument. Even the first argument is a bit of a dead end because the data is so vague and the data points so few there's very little to extrapolate upon. For instance: Canada sells relatively more PS3's because of Quebec (i.e. French-speaking, i.e. France, i.e. mainland Europe AKA PSLand) =
