So Sony said they sold to consumers more than 10mill at Gamescom (August 9), now almost 2 months after, PS4 only sold around 1mill more with Destiny's launch???... I don't think so.
I think that by 20th september, ps4 numbers would be more around 11'5-12m than 11m....and i won't be surprised if in the first week of October PS4 surpass 12 mill....
