The January drought is over, that's the main reason for the increase. With that said I'm still surprised at the Wii U numbers and the PS4 numbers compared to last week. I actually expected PS4 to drop considering it hasn't had any major software releases recently, and Sony needs to build up inventory for the Japanese launch. These numbers suggests PS4 production has increased to meet demand. Quite impressive.
When it comes to Wii U, I'm very surprised that Wii Fit U isn't on the software list this week. I expected that game to sell 12 000-15 000 copies in the US this week. I'm also surprised Wii Play U isn't in the top 20 in the US; I had it at 10 000-12 000 copies.
Still Wii U numbers are way off from my December predictions, where I put its weekly Q1 sales world wide at 75 000 systems.
