Be patient Ail. Media Create and Famitsu showed opposite results last week - MC had Wii up to 32k Famitsu had it at 24k. One was up 3k, the other down 3k. Famitsu covers more Gamestop like specialist retailers than Media Create does, while MC has more big box retailers for "ordinary shoppers" which is why you have MC 30% higher than Famitsu last week.
Media Create also had PS3 higher than in Famitsu. Software sales were also a lot lower.
It switches week in, week out, and it usually evens out by the end of the year.
