Srry but thats kinda...... Too much. I would of said 14mil-15mil this year was achievable but it sold less than 5mil, its not going to sell 10mil with nothing in 2 months and no huge Exclusives. 2015 is going to be bigger than 2014.
I see PS4 at 15mil-17mil by years end. Still be by far beating X1+wiiu :)
