Something doesn't add up...
Geoff Keighley said "Sony has announced 18.5M PS4s sold through worldwide to date, including over 4.1M between 11/23-1/4".
Reuters said "sales of its PlayStation 4 video game consoles exceeded 18.5 million units as of Jan. 4, up from 13.5 million at the end of October".
That means from November 1 to November 22, they only sold 0.9 million (18.5M - 4.1M - 13.5M), or 300k per week? That sounds too low for November. November numbers are usually 1.5x October numbers, and not 1.0x October numbers.
I think we'll have to wait for the end of the quarter financials to know for certain.
