308k during holidays with big exclusive system seller = not that great.
322k, sold out almost everywhere on february with 0 exclusive game appealing to japanese = great.
Or is it too difficult for you to understand these simple facts? PS4 has a much better futur than Wii U obviously, it will be the main home console in Japan to play multiplatform games and will get all the exclusives.
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
