will this will be a hard one. specially since you are asking us to predict sales of the consoles up to december next year, i mean its mid quarter, you should have made the prediction to either end of Q3 or Q4.
im predicting
PS4 11.2 million
X1 9.6 million
WiiU 7.8 milliion
3DS 51 million
Vita 9.4 million
im 99% sure that i am going to be wrong though
