Wow! This is the first time I saw someone that took VGChartz estimated numbers to heart rather than taking it with a grain of salt. Oh wait! There's people from N4G who does that regularly, my bad :p
I would love the X1 to win the US too but it looks like the PS4 may have edged it out this month. Using the Amazon charts as a barometer has not failed yet. So going against it isn't wise, I should know, I doubted it months ago too.
