Overall I think VGC really tracked it right (maybe a few thousands off but for sure within margin of error).
Now we have official WiiU,PS4 numbers, I hope we'll get 2014 numbers in January for all 3 consoles (We don't have any XBO numbers since 126K as of the end of last year...)
Prediction: End of 2015 Hardware sales (as of January 20, 2015)
Wii U: 12.1M | XBO: 19.8M | PS4: 36.0M | 3DS: 58.5M | PSV: 11.7M
