I am going to assume you are talking about home consoles only.
I don't know- PS4 has a shitload of hype - i see it selling shitloads. Until i see how the market reacts to the PS4 - i think it is still safe to predict the last gen will have it beat - but i wouldn't count the PS4 out.
I am going out on a limb and say that 2014 will be a tight race between the PS4, One and Wii U - with the PS4 coming first followed by one then the Wii U but still be outsold by the ps3/360
