I think PS4 will reach 16 million consoles by December 31st, while Xbox One will do about 8 million.
These are the ranges I'm expecting for this gen:
Xbox One 37 mil +
PS4 sales 122 mil +
Wii U sales 12-18 mil

Bold predictions all around.
Are my predictions not bold enough?
I plan on putting more bold in the future; I DONT WANT U GUYS TO NOT HAVE FRESH, BOLD PREDICTIONS EVRY COUPLE OF WEEKS OR SO!!!
