Sony's E3 games were pretty good so I'm not sure why he said that. I guess some of those games don't appeal to most people, and their line up for the rest of 2015 is kinda bad.
Why bad ? They have as much exclusive on PS4 than Ms on X1, and even more in fact, no need to be a AAA.
They are just saying their exclusive first party line up was weak this year compared to what we are used to with them, but that doesnt mean they dont have 3rd party exclusives like Dragon Quest Heroes
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
