So the ps4 just passed the Wii U at around 3.2m units sold.  What consoles are next in line?  

 

1) Vita

2) PS3

3) Wii

 

And then later on we will see if the NX can beat the PS4. 

I don't mean just current Gen comsoles.  I mean from all time.  so it would include gamecube,  Saturn,  vita,  PS3, Wii etc.
