I actually think that the Xbox 360 will sell the least this holiday and the PS4 to sell the most. Xbox One will sell a lot also but less than PS4. The PS3 will sell good I think and Wii U will sell better than Xbox 360.
So most to lowest I think.
PS4 - 4 m
X1- 3 m
PS3 - 2 m
Wii U - 1.5 m
X360 - 1 m
But it's very difficult to predict PS4 and X1 since we don't know exactly how many consoles will be available.
