这个数字怎么得来得
Where do the numbers come from?
The console sales numbers you see on the front page of NexGen Wars are estimates, and are not intended to represent exact, down to the minute sales as only Microsoft, Nintendo, and Sony know the exact sales figures of their respective consoles. What we do here at NexGen Wars is compile numbers from NPD, Media Create, ChartTrack, as well as various other sources. We then take these numbers and, based on past sales trends, extrapolate the numbers out to give as close to real-time estimates as possible. Again, these are only estimates, but we are confident in our ability to bring you accurate and unbiased sales figures. Not only do we extrapolate the numbers out so they don't lag months behind with the official sales numbers, but we also update the numbers when new official numbers have been released to keep our estimates as accurate as possible.
