Here is a little calculating aid to help you make sense of those weekly numbers.
It is so rough and ready it's unbelievable.
Take a weekly number from Japan or North America, multiply it by a thousand, and that's the lifetime sales. Â
Put another way, take the thousands in the week and turn them into millions.
The reason is that there are three major markets and 52 weeks in a year, and a generation is about 6-7 years, and so there are roughly a thousand weeks sales per console.
Obviously this takes NO account of variations in sales.  But for example we can say ...
PS3 did 20K in NA, that's 20 Million lifetime, that's kind of Gamecube sales.
PS3 did 8K in Japan, that's 8 Million lifetime, that's catastrophic.
Wii did 120K in NA, that's 120 Million lifetime, that's PS2 level.
It aint much use for the 360 since that varies so much.
I promised it was rough and ready and I wasn't lying. But it does give me at least a feeling for what 20K or 50K or whatever means per week.
