My estimates for the end of 2014 still hold, and they will decide which way this generation will go, to a great extent (clarifying more about the assumptions made).
End of 2014 sales estimates
PS4 : 13.7 - 17 mil
XB1 : 6.3 - 9.8 mil
Note that I made those estimates at the beginning of this generation, and they still make lots of sense. I remember many people criticizing my PS4 to be "too optimistic" and there was no way that it could compete with PS2, we will see. Then there were some people who thought XB1 would be doomed and would never sell over 6-7 million. My estimates are a minimum of 6.3 mil for XB1 (and roughly around half of PS4, by the year end). All this still makes a ton of sense. My estimates will be more precise after this year (and we observe the trends better).
