Your math doesn't add up. PS4 is $400 PSeye is $50. Where is the unaccounted $50?
Not only that, but a PS4 bundle with extra controller, PSeye, 500GB system, and a game is only $500. If that's not a slit to Microsoft's throat I don't know what is.
So next time you see your source, AKA Dave from Worst Buy, tell him he needs to check his facts.
