Poor Ioi. He's Harassed when the numbers are a few minutes later than usual. Then shouted at when he rushes to put out the numbers and makes some errors due to data anomalies. We recognise the hard work that Ioi puts into the site as well as keeping a full time job.
Maybe move all updates a day later to allow for all the data to come in and be tinkered with properly?

Maybe the people who are complaining can join other tracking websites. A rival website currently has the PS3 & Wii 1.5million & 2.6million lower than VGChartz.

There are no rival sites

Actually, there are

For example...

 From nexgenwars site:

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.

So, they are not doing ANY data sampling.  They take data of the above mentioned sites and "based on past sales trends, extrapolate".  Now, while that gives a nice rule of thumb, that November sales will be double October and double again in December, any new changes in buying habits are unknown because there are no samples to base those changes off of.

Even tho they are getting the data at a region level, NPD=US,  etc., the numbers are reported at WW only, so you can't compare to say, oh, this number must be off based on the new NPD number.
