PS4 behind WiiU in it's second week in NA? What's wrong?

[Dark_Feanor]

3mi until 31th... it gives less than 250k a week, 100k for EU so... yep, WiiU might outsell PS4 in NA for some weeks this hollydays.

Considering how the PS4 demand would be so strong WW I´m starting to think Sony may have played not so smart forcing a little shortage in NA and other places.
