not trying to spin this, but was this a full week? I know that when we get the US Numbers it will be only include 1 day. I know a good majority sell the first day, but if Japan didn't have a full week we could easily see a 2nd week of 15-20k for people who didn't even know it came out.
Even here in the west I know a hand full of people who didn't buy MK 8 during the 1.2 million period. I also know a couple people who have to wait a week to buy a Wii U until they get paid next. (I know they should have bought it the payday before, but didn't buy into the hype until after it was released)
