Based on what logic?
Ok, Sony came out with some ridiculous $800 console, like a year after 360 came out, that just drove more people to xbox 360. (this time xbox has the dumb expensive console, hence the statement not reading "million sold in North america")
Sony wanted to be the all in one media console with the PS3, Microsoft was all about gamers. Xbox fans clowned Sony for that. Now fast forward to today, not only are xbox fans apologist for the Sony type "take over the living room' tactics Microsoft is deploying..... Basically Hypocrites
M$ still has the exclusives they dumped millions on, cause hell something had to go right for them, Titan Fall will be their system seller.
This time around, Sony is gamer friendly and it shows in sales
Sony is the cheaper/more powerful console
Let's just say this because I don't have time write now to even go back and edit and make what I typed above coherent (my bad I just got up)
Courtdog best to buy a super hero costume because he is going to have to work double hard defending M$ this gen
