september, october, november, december.
4 months.
1 month = 4 weeks
4 month x 4 weeks = 16 weeks
if ps4 sells worldwide about 120,000 consoles per week...
120,000 per week x 16 weeks = 1.920,000 consoles worldwide to the end of the year 2014.
10,1 million consoles + 1,920,000 = 12,020,000 total consoles in 1 year and 2 months in the market.
as i said, is very difficult to sell 14 million or more but not impossible.
