Honestly with all the hype and early phenomenal sellouts for XBO and PS4 it is so hard to predict something like this. We don't really know how well each are going to sell during some of the bigger gaming drouts of their lifetime or once the hype dies down. WiiU also has some bigger games coming and 3DS is just a beast. PSV also may gain some traction with PS4 on the rise.
Luckily XBO and PS4 each has multiplatform games as well as some exclusive titles such as InFamous and TitanFall in the first half of the year which has both reached over 100k preorders by this point.
So by the end of 2014 what do you think each will have sold.
I will be keeping track of each prediction below
