Can the PS4 catch the 3DS before Nintendo discontinues it?

[Turkish]

It could in the last year of 3DS' life, I expect 3DS to be discontinued in 2018, it will sell between 70-90 million.

Here is what I expect PS4 to sell like over the next years
LTD at end of the year:
2014: 18 million
2015: 33 million
2016: 49 million
2017: 64 million
2018: 77 million
2019: 87 million
