@pilias_simber, I have personally calculated the correlation between US and Canadian NPD figures for May here. April numbers also range from 6-10%, with only the Wii numbers deviating, but even then, it is not that much. There is definitely a good correlation between the two numbers.
I also calculated June's correlations: Wii-9.43%, DS-11.97%, PSP-6.38%, 360-6.8%, PS3-6.6%.
If I remember correctly, April correlation for the PSP is also at 6%. Not only are the correlations ranging in a narrow 6-percent spread for 3 months, the PSP's correlation is the most stable of the consoles.
Now I'm not saying that this correlation will still hold true this month, I even think it's rather impossible given the exceedingly low PSP numbers for Canada, but a lower than usual sales for the PSP in the US for July is a big possibility.
