So 2 separate predictions and a poll for one of them.  When if ever do you think the PS4 and x1 will triple the Wii U in total sales?  

 

Firstly the PS4. I estimate the Wii U will hit 12m by the end of 2015.  Could the PS4 hit 36 million and triple it this year?  I'm predicting it does it by first quarter 2016. 

 

X1 is a lot harder to predict.  I'm going to say Q4 2018. Let's have your prediction!  

Starting to doubt they will. The Wii U and X1 are actually up YOY while the PS4 is down YOY. Since that is happening, I'm not sure it will. 

Sony recently released numbers showing they are up YOY.  This sites numbers are wrong.  

 

But I don't think you get what I'm saying.  I'm asking when ps4 triples wii u meaning will it get to 36m while wii u is at 12m for example.  And I'm asking separately when will x1 triple the Wii U. I'm not asking if ps4 will triple x1 plus wii u combined.
