I'm positively baffled at how the hourly charts work now :-3. I mean, when we know that the Wii U was the bestselling item since tuesday, while the PS4 has been the #1 item on the hourlies all the time, that would mean the hourlies are a running average of 5 days+. That, or there's some other, non-sales related stuff factoring in. Or they are starting to do advertisement-based charts :-/
Oh and OP updated with monthly numbers.
