I don't think you guys should jump to conclusions about this. There are plenty of possible reasons which don't involve Vgchartz making up numbers:
- retailers sending preorder numbers to vgchartz
- midnight launch numbers being received
- wrong parameters given to an extrapolation formula
- more reasons I didn't think of
- a combination of several of the above reasons
