Yes, because of the numbers Nintendo provided. The X1 is a wild guess, as Microsoft has been secretive about it's numbers for a while now.

Thought process as to why PS4 at 11 mill?

End of this month.

The number of 6.68 million Wii U's shipped given by Number was for which date? does it include july? we know the npd american sales and the japanese sales of july.

you came from a future where the Xbox One has crossed 9 million haven't you?

Nintendo have confirmed that Wii U have sold 6,700,000 million?

Nintendo have confirmed 6.68m shipment by 30 June, and according to VGchartz have sold 6.54 million by 28 June...

I agree with the Wii U overestimate, but by 250,000-300,000? nope.

Between 100,000 and 150,000 in my opinion.

Ineed, the week of 16 Augost, Wii U have sold 6.96 million for VGChartz, i think that the real sales is 6.85 million, Wii U sell 50,000-60,000 in one week, so in 2 week between 100,000-120,000, and the total sales are 6.95m-7.00m, IMHO.

As of June 30, 2014

VGChartz' comedic undertracking of the PS4 is getting weird... Anyway, I'm down for:

PS4 - 10.4m
Xbone - 5m
Wii U - 6.9m

PS4 10.4M
Wii U 7.4M
Xbone 5.2M
