According to hardware sales data from Media Create, the Xbox 360 didn't manage to outsell Nintendo's Wii during the week ended September 14, as earlier reported by Famitsu.

While Famitsu pegged Xbox 360 sales at 28,681 units, 1,600 ahead of the Wii for the week, Media Create reckons it was the other way round, although still a close run race.

Media Create data sees the Wii leading the battle of the home consoles with 29,686 units sold, followed by Xbox 360 with 28,188, PS3 with 8,053 and PS2 with 7,669.

According to the firm, handhelds continued to lead overall hardware sales, the DS way out in front having shifted 63,859 units, no doubt boosted by the release of the chart-topping Pokemon Platinum, while the PSP narrowly managed to outsell the leading home consoles.

DS - 63,859
PSP - 30,156
Wii - 29,686
360 - 28,188
PS3 - 8,053
PS2 - 7,669

Sales data compiled by Media Create.

so are media create more reliable than famitsu?

VGC and Famitsu can't both be wrong...?

For all intents and purposes, it's a tie. All 3 datas are way too close.

Sampling error. You can't expect accuracy down to the hundreds, let only single units.

people have accept the fact that 360 out sell Wii.

There you go I fixed it for you.

The difference between Wii and 360 sales is within the margin of error and therefore statistically insignificant, that's all. The three trackers are bound to fluctuate around the true number sold.

In other words, it has always been inaccurate to say that 360 beat Wii sales in Japan this week. More accurate would be to say that their sales were statistically equivalent.

There is already a thread on this.
