This is ridiculous. It won't come close to 115m.
It's currently at 70m after 6 years selling at an average pace of ~11.4m consoles per year.
It needs to ship another 45m to reach 115m. At best, the PS3 will have another 4 years of life (and that's being extremely optimistic).
In order for it to sell 45m within 4 years, it would have to average ~11.3m consoles per year.
Considering it'll only sell 11-12m this year and even less next year, there's no way it'll average over 11m for the next 4 years. It's final 4 years aren't going to match its first 6 years.
And that's assuming it'll be on sale for the next 4 years. It may be discontinued. And if its not, it will only sell tiny amounts (4-5m per year) during 2014-2016 until it finally dies.
You should have just predicted 100m. It's an excellent milestone and is actually possible.
