September 2016 will have been about 34 months of the system's life, it's already sold 20.2M in the 1st 15 months, leaving 29.8M to sell over the next 19 months, or an average of 1.568M a month, very easy IMO!
Considering that the 1st 15 months had the weakest library of exclusives and the highest price the system will ever have it's already achieved an average of 1.3466M a month over the last 15 months.
A price cut is highly likely this year.
PS4 has 17 outright exclusives in 2015, with Sony already confirming that they have more to announce for this year. GT7 is likely this year, on top of a new Killzone and probably a few others as well.
2016 will have Uncharted 4, Without Memory. The new God of War is likely for March, Guerrilla's new IP, probably a new Sly Cooper to release alongside a heavily marketed movie, plus loads of other surprises.
2015 is much better for exclusives than 2014, 2016 will probably destroy 2015.
50 million will be easy to achieve by September next year!
