He is against how Sony priced their console and features that PS3 has that may affect the price. Then posting sale figures of Sony's top holiday games: LBP and R2. Then stating how it was R2 vs Gears2 and Gears 2 clearly destroying R2. Both of their top holiday games doing badly compared to others.
I understand his reasoning of going to xbox, he just made it seem like it was about sells. He just doesn't like how sony is using the PS3.
I think LBP and R2 had good sales but if you compare sales to hype and other games of their genre like Gears 2 than their sales aren't so good.
