Calling it Sony's biggest mistake is an exaggeration.
When I think of Sony's mistakes I think of Minidisc, Betamax, complex and expensive Ps3 architecture, failure to respond to the ipod and failure to create synergy between console, pc and mobile content. The fact that GT6 was on the Ps3 is to be expected doesn't even make the list.
